I guess my issue is this: if you're a person who ends up being discussed in an anonymous meme, it's hard to defend yourself. You know nothing about the person or persons commenting, you can't figure out their point of view, you can't even discern their real opinions. It's hard to respond in any manner that doesn't make you look childish, because you're forced to make assumptions about the other person or persons that may not be fair or correct. At least if someone uses their LJ name, you can at least visit their LJ and figure out their point of view so you can respond in a reasonable and sane manner.

Why would anyone want to defend themselves against anonymous hate? It's like going over to Fandom Wank and trying to seriously defend oneself, sure one can, but why? I've been hated on in some really really ugly hate memes and so have some of my close friends and yeah, it's not fun, but in most cases I was pretty sure who the haters were and nothing we could say was going to make them change their minds about us.

The thing is, people who post on anonymous hatememes don't want to discuss things in a "reasonable and sane manner." If they did, they wouldn't be posting there.
