How do you deal with ignorant comments?

You trusted someone with something they had no way of processing. Ignorance can be corrected with knowledge.

If you had liked this person up till the time your told them of your diagnosis, give them them a chance and send them some links they can use to understand. Engage with them to help them understand.

If they resist - they have already decided to stick with contempt and skip the investigation.

This is valuable info for you to have, too: It says You are not important enough to them to bother going into new territory to get to know. 

Don't judge them, just know that the only way someone else can hurt your feelings is you give them permission to.

we are all busy with our own challenges.

You'll be o.k.
Keep plodding on.
The ASD journey is a long path i suppose.
You are right, don;t give too much away too soon.
Hey, if YOU are weird then so am i !   What You posted resonates exactly with My experiences.
Remember...It is not YOU..it is all the rest of them  

I hope to have that same confidence to tell work people eventually and challenge their views. You’re absolutely right that how much energy we have determines how we deal with people. Perhaps next time I hear such a comment I’ll try questioning them and see how that goes 

This is so similar to my experiences, and I’m sorry you’re going through it as well. It’s just so disappointing isn’t it. I also am not comfortable telling management. 

if I ever hear people using outdated language or offensive terms I’m pretty quick to challenge them and argue my point. But when it comes to my own autism I clam up. Like I want to shrink away so as not give the game away
 
I wish I had advice to give I really do. 

I tell people at work quite freely, if only to challenge their stereotypes. Am 52 just diagnosed Feb this year, and I think I am reaching the point in my life that there are a few people whose opinion I value, the rest of the world has a lesser impact (at least, today it does!!). I am still reading up on it, particularly lived experience books, so I can understand better how it works. I don't think I knew anyone autistic until I babysat an 8 year old when I was in my 20s, and I turned out to be his favourite babysitter because I was clear and consistent. I just thought he was quiet and introverted... but then I wasn't playing loud music/TV... That kind of consistent that my sister called me supernanny when I looked after her kids.

Friends: I told some, most reacted "so...?" as it wasn't important to them, or they weren't surprised. One friend I hadn't told, started complaining about her friend's violently autistic grandson, so I felt duty bound to set her straight on that one, then told her my diagnosis so she knew where I was coming from. She was pretty disbelieving at first (in her late 70s and only the stereotypical image from the media), but then got it. Since I wrote her a massive post with information, I haven't really heard from her. But we are only in contact sporadically, so not worried.

Family: not told any of them (sister, nieces, nephews, mum, aunts & uncles, cousins) for the same kind of reason. It would serve no purpose.

How I deal with ignorant comments... often a raised eyebrow and a smirk, sometimes I set them straight, sometimes I question their assumptions. It all depends on how much energy I have at the time.

I have worries at work like you. I've not told anyone at work. But they laugh at the guy in the office who they think is autistic and laugh at the lady there who they think is 'weird' who I think is autistic. This goes for my line manager as well.

They also have made comments about how "everyone is wanting to get diagnosed with autism" for financial reasons.

I meanwhile am mortified and failing at my own masking.

It makes me despair of people in general.

Thank you, I’m glad I’m not alone in thinking such a comment was as bad as I thought it was. 

I shall absolutely be overthinking it for days  

I feel better for getting it out though. It’s nice to find people that understand

Thank you 

As I’ve gotten older I do share a lot less with people but every so often I do the same thing (talk then analyse!) it’ll be on my mind for days now   You’re probably right that I confided too soon. I’m often too trusting and assume people will treat me how I would them. Unfortunately that isn’t the case and I need to learn that. 

Thank you for making me feel less weird about it  

Hi Iris. Welcome!

Their reaction was awful. It's such a shame that this happens a lot, and sometimes even from family.

Truthfully, how do I deal with comments... by it whirring around my mind for days on end. I think a lot of other people here do to. We are prone to rumination.

At least you have us to listen and maybe give good (and bad) advice.

Try to go easy on Yourself.
Maybe You confided in Someone too soon.
ASD ( especially with Myself ) tends to make me talk before i think, then i analyze after and think
to Myself  " Why did i say that ! )
Don't feel like an idiot, You are not.
I think ASD is a bit of a learning curve.
It is not You, but simply how we are.
Keep smiling  

I enjoy a bit of sarcasm too  

I mostly just felt an idiot today because I opened up (which I don’t often do) then got met with a not particularly nice comment. 

It’s something I often think about, though as it’s only been a few months I’m still coming to terms with it all myself. I will probably end up telling them though it will be when it feels right to me.

It’s just the first time I’ve dealt with a comment that was rude. Because the only other people that know about my diagnosis have been supportive I naïvely thought this person would be similar but they weren’t. I felt like an idiot  

Like I deal with any hard competition. I do my best to keep my face straight, my demeanor non-comittal, and if there's any slightest chance that I'm not quite sure how to take it, I keep being nice. It's not their fault that I dont; understand their bullsh7t it's my own limitations.

Occasionally I get all my ducks in a row, and start hacking away with the sword of truth, the one with the withering sarcasm engraved upon it.... 

As a contractor, you can really come to enjoy sarcasm iin the workplace.

Do You think it might have been a good idea to inform Your Management at work ?
That way they can acknowledge and monitor Your well-being in the workplace.
Equal opportunities and duty of care etc..
