Is this really a safe space for autistic adults?

Recently I have noticed more comments by partners and parents of autistic people, and quite often they are derogatory towards autistic people. 

Do other people feel that this is a safe space? 

In particular, I'm upset by the thread questioning the validity of celebrities being diagnosed as autistic. Many of us have had a lifetime of struggling and discovering we are autistic is empowering as we finally make sense when so much often hasn't made sense pre-diagnosis. I don't feel that we should have to be faced with people questioning that in one of the few spaces designed for us to discuss our innermost thoughts and feelings. Sometimes I actually wonder if we are even being trolled and people aren't what they make themselves out to be. 

I just wanted to get that off my chest because I'm upset and anxious after using the forum tonight, which isn't a sign of safety.
