90% of comments made by random strangers are not very personal; if you want to tell when a reaction is personal, its more obvious in which the person will go out of their way to sperg for more than 1 time. Its not a Kiwi farms or 'evil dark webs' exclusive thing, every website does it. Real life is kinda like that too of some jerk giving you an off-hand comment about what you're wearing etc. Some comments seem extremely judgmental and horrible, but those comments tend to be exaggerated and the person behind the keyboard does not (honest-to-God) feel that way.
Cyberbullying is a meme, especially to those who've actually experienced being bullied at one point in school. When someone calls you a fag on the internet, you can block them; but if there's a bully in your school who's picking on you and rallying kids to dog pile with him, you can't really escape from the bully as easily as the internet. If you tell on the teacher, your school reputation is 'ruined' because the kids will call you weak, and transferring to another school is costly.
I don't know if normals know about this whole thing, but I won't judge them since I've never been social but I'm slowly trying to- not jump into love relationships, I think way too many people try to do this and its more than they can chew. just a genuine friend I can trust, and can get back with again and again when one of us gets irrationally grumpy occasionally.
