I've been giving this a lot of thought and this is what I've come up with (and this applies everywhere on the Web, not just on PA).
I. I've encountered this kind of thing a few times on YouTube. If we are talking strictly bullies, hardcore bullies, ... unfortunately,
the best thing to do is to ignore them. Tempting as it is to just tell them off, it doesn't work; my theory is that's what they expect you to do. I personally don't understand this kind of mentality myself, and tempting as it is for me to try and understand this kind of mentality, another part to the aforementioned theory is ... that's another thing that the bullies expect of you.
Just don't bother with them. Think of them as spam.
II. However, if we are talking the kind of people who tend to get emotional or senselessly arrogant every now and then; the kind that tends to use negative language ("Apparently, you don't know this or that", or "Obviously, you've never been here or there"), the kind that tends to make disparaging remarks about someone's intelligence; or the kind that makes indirect, sarcastic remarks* (maybe not with malicious intent), then I recommend the following options:
0) This is imperative: choose your words wisely. Think positively. Be sensible, not sensitive. Pay attention to the language you are using (as mentioned in the paragraph above). Some people just don't care for that, but I hope you do.
1) Try to trump you feelings about what words that person used and try to have an intelligent conversation with that same person on a different topic;
2) Try to trump you feelings about what words that person used and put yourself in his/her shoes, look at the topic from his/her angle;
3) Ignore them. Don't say anything. Making a remark about the person to anyone or anywhere will accomplish nothing and it does not help the forum on any level in the slightest. Don't try to correct anything or anybody or investigate into that other person's nature. If you've tried all the points above that I've suggested, then you probably know: it's not you.
Never take anything negative too personal. If I see someone talk crap about what I said, I think "A-a-a-ah, crud!" and move on.
* Sarcasm works here about 50% of the time. In any case, I would not encourage it here on this forum.
