Bullies are everywhere. Honestly, even more so now because they can hind behind a phone or computer and type their hatred. Long gone are the days where you were actually confronted with a bully, yes, it does still happen but not as often. You have to take what people say as a grain of salt. There will always be someone saying inappropriate comments, especially if you're on the Internet. Know your audience before you stream. I understand you want to stick up for your friend but in order to fix the problem he should be dealing with it himself. Not a friend posting a plea for support. Autism sucks but it can be managed. Something he must come to learn.
