That only really happens to me if someone wants to cherry pick something I said and try to pick a fight over it. In which case I'll either ignore it, or say something that will bait a response and then ignore it. Schrodinger's Reply can't hurt you if you don't look in the box.
It depends. I've had people give me constructive criticism about how my OP writings are too long. I have typically thanked the user in question and have then ignored the comment.
Some attacks have been personal. I've had people at other sites tell me that I've made up stories about my life and experiences because nobody with autism could possibly have been a teacher for 32 years as well as having been an expat in 5 different countries over a 17 year period. I have ignored these people as trolls but have also usually left the forum in question.
Some people complain about the same problem over and over and over again. No matter what constructive suggestions are offered, the OP has a reason as to why none of these suggestions will work. Having decided that this person may be using others as enablers for his or her continued complaints, I will ignore the person in question. If too many people in a forum are making similar complaints, I will typically leave the forum because these peope seem to feed off each other.
Sometimes people will disagree with me. That's Macht nichtsto me as long as the disagreement isn't phrased in personal terms i.e. "You're stupid because ___".
At another site, one person jumped on me after I responded to a question about what ABA therapy was. I was at the time pursuing certification as a special educaiton teacher and ws in the middle of taking an ABA class. While this most certainly DID NOT qualify me as a therapist, it did provide enough information that I could articulately talk about what ABA therapy was.
I replied to the ABA's question and was then attacked by someone who wanted me to know how bad ABA therapy was. I explained that I was a teacher who was pursuing additional certificaiton and that I was not an ABA therapist. I further explained that I had been only responding to the OP's question. The other person pressed his point of view by continuing to tell me how much harm ABA therapy had done. I finally responded by saying that this person was not my supervising administrator or university professor. He did not have evaluative or grading oversight of me. I didn't have a choice regarding my participation in an ABA class. It was a required course for certification.
I wound up leaving the site in question. To be fair to the critic, he/she did not respond to my last reply.
For me, I guess it depends on what they have said that has annoyed me, and also how well I feel I know them. If I feel compelled to comment, I will try to do so calmly. If I'm incapable of that, then I'll try to keep my thoughts to myself.
