The problem with lolcow is that it's already the only universally accepted term to describe this phenomenon, regardless of how "icky" it's connotations are. There's really no word for it otherwise. Trying to change it to some other, more politically correct term isn't worth the effort and isn't really going to do much anyway. I understand that you're a big advocate for treating lolcows like human beings and such and not sideshow attractions and that's great but you have you realize that:
1. you're a minority in this regard
2. you really can't force anyone to adopt this more enlightened, more humane view, as nice as that would be
3. trying too hard to suppress "cannibalism" can only ever lead to homegrown lolcows like PvtRichardCranium getting away with being toxic lunatics forever and bringing everyone down with them, forcing everyone to put up with their shit because nobody is allowed to be mean to anyone ever or call anyone out for anything because mean isn't a real word in CWCville, we use the term "Flesh-Entity of Negatively-Connotated Disposition" here thank you
tl;dr You're not going to change a culture by changing the word that represents the culture, because words are just that: representations. They hold no power by themselves. People trying to get rid of the word "nigger" didn't really obliterate racism, they just made suburban white people say it in private instead and complain on Twitter that it was a violation of their rights that they couldn't say the word. I don't want this forum to become suburban white people
