Humans as a whole are likely to look to themselves as good, to see themselves as above the petty, astonished at the kinds of words and expressions that would escape another only to deny that very evidence in their ultimate evaluation of humanity and its evolution over the savages of times past who might as well not count as actual people for their misdeeds. The very word "humane" exists in description of a forgiving and compassionate attitude, our standards for what would constitute decency so great only for our collective greatness taken for granted.*
Except then you can bring anything regarded as bad writing and relatively well-known and the common man will work to pave all roads going straight down to hell in a fortnight several times over.
Justin Bieber, Michael Bay, Stephanie Meyer, Kawahara Reki, it's not as though I personally like any of these people either. (Well, honestly, I know close to nothing about Justin Bieber besides him being generally shit on.) However, I've said before that it's like people are looking for an excuse to hate for it's own sake when they go on to focus so much on these particular individuals, and now I'm thinking, is that the real reason why in such circumstances, it becomes so easy for people to get on a high horse when feeling like being an unabashed slanderer?
People know who those are, people can find what they've made as well as several news articles on them and a significant community to fall back on, and are without need to generalize those persons as a group. They can turn hatred to unified discussion and cultivate its reasoning, and at the end of the day, walk away and tell themselves they're some of the nicest people they've ever met. It is good and socially acceptable to look to another's work and take it as evidence for speaking against the creator's character, a cultured, virtuous, and mature activity for one to have themselves partake. However if they were to say the same towards an unknown or the everyday person of the streets publicly, they would have no chance to retain their integrity, either in the eyes of others or for those who are of any self-awareness, the eyes of the self.
That it would be easier to excuse is clearly evident, but then comes the question, why is it so interesting for people to band together in hatred? I speak as a hater, I know what hate is like, on the receiving end and on the assault. I know that it is less a decision and more of an impulse in contrast to what many would suggest to give themselves the opportunity to look down on the likes of me. I know that it isn't really an enjoyable thing to be feeling, and without evident results to come alongside it, it makes me look to myself even worse. The hate people will have for these kinds of people are unlikely to have serious effect on them unless they are the kind of people who would commit suicide after receiving one too many death threats or something of the like.
There is only one reason that really comes to mind for the reason why so many would revel in camaraderie born of malice, and that is what I was once told by another who spoke well of the community they were among, only for how it was too busy directing most of its hatred towards the game company to hate on each other. That also got me thinking about the communities out there that talk a lot of shit towards another community...they may take jabs and jokes at each other's expense as many would disregarding the insults as mere friendly banter, but if they want to get serious on feeding the ego, it's best to go all out on someone that won't bother talking back.
*Some time ago I was in discussion with someone who was, as relevant to the topic at hand, going out of their way to debase a protagonist and its author of something they never bothered to even read. This same person will look to someone(the protagonist they're talking shit about) that will willingly endanger themselves into going further into an extremely life-endangering situation for people that very clearly tried to screw them over, and disregard this act of heroics as being anything just any good friend out there ought to do, even though they themselves go about sneering about in contempt for those they find beneath them. That we mutually find each other a laughable existence is no coincidence.
