This!
And it is bullying behavior. So if someone exhibits this behavior 20 times to 20 different people it is not bullying but if they do it 20 times to one person it is?
If you say that X is lame then you are implying something about people that like X, aren't you?
But even in my example it doesn't reach the level of bullying unless it becomes relentless and interferes with your life. Yes, they may be making those comments in an effort to feel superior to you, but that in and of itself is not bullying.
So if you love Universal it would have to involve the other person harassing you for weeks on end. Say it is a coworker-- if everytime they walk by your desk they make a nasty comment, they convince every one else in the office that they should ignore you because you love Universal, get others to pick on you because of it, leave things on your desk like torn up Universal pictures and Universal stuffed animals hanging in a noose, drive by your house and spray paint "Universal Sucks" on your lawn, prank call you at all hours of the day and night with nasty messages, tell you that anyone that loves Universal should just curl up and die, and wait for you in the parking lot and throw Universal souvenirs at you, then maybe after several weeks, and probably a reprimand from the boss (and the cops!) they ignore, it may reach the level of bullying. It has gone from a difference of opinion to threatening and is affecting your sense of security, your ability to live your life, and for some people the ability to cope.
In this case the issue is most likely not even about Universal, but just a dislike of you personally and this is just something to latch on to and use to intimidate and humiliate you. Much like with teens it is often one or two things they specifically harp on like a haircut, sexual orientation, how they dress etc.. The bully has an issue with the whole person but picking one or two details is the way to direct the harassment.
I think the issue here is what is the difference between harassment and bullying? On a message board there are a lot of options to make sure that this behavior doesn't affect your daily life, starting with the ignore function and ending with just not visiting the site. Yes, I have seen and heard of harassment going on on message boards, it happens. Someone starts PMing you to argue the issue. They follow you to other threads to keep bringing the topic up. If you are going to be on the internet and going to express your opinion and get involved in discussion then you are opening yourself up to that. That is why the phrase "flame proof suit" is around. But this is not bullying. No one is going to go and hide in their room and refuse to go to work or school because of a disagreement with total strangers on a message board (at least I hope not!). You are not going to od on xanax because a total stranger told you that you are lame and an idiot for your opinion and people like you shouldn't be allowed to breathe. (the universal You, not addressing anyone in particular) They may be rude and obnoxious, but that is not bullying.
But if the online harassment is coming from people you know. People you see and interact with everyday and they are escalating to the level I talked about above then you start to see bullying. Which by the way I really don't understand. If someone is getting this treatment on FB or email or IM then why don't they just unfriend, block etc the person(s)? That at least takes that part out of the problem.
