Not too much you can do to avoid that kind of conflicting drama.
Like, if the furs there are determined to be tailholes, you're not going to convince them to change. If you make your own site to replace theirs, they'll all call you the tailhole. If you don't make your own site, you choose between being like them and liking what they want and not liking the people they don't like or, doing nothing like you're doing now.
A fur group that's only interested in anime and video games sounds pretty sad to me. Why don't they go join an anime fan group?
Out here around Toronto we have a clique like that ruining things for others. Here it's all about alcohol and drugs and making fun of the uncool furs, and nothing really furry at all. Ironically, the uncool furs seem to be the one's more interested in furry stuff.
I figure if you have a good idea, why not go ahead and start something. If that clique wants to snap at you over it, oh well, it's not like you're loosing anything if they hate you.
As for finding other furry and getting a group together, google can be your friend.
I've found the best way to get to people is getting IM's and e-mails and contacting them directly. Making posts works too, but people miss those.
For the old Toronto Furry web site, I started hitting google with things like "furaffinity ontario" and would go through some furry message boards members list finding furs located in Ontario. After a few months, I had expanded it to an Ontario wide site with over 400 furries listed on it.

In spite of things, we've have managed to get a really nice furmeet going, thanks to Ki Wind giving us the space in his building's party room:

Yeah, we still had some games and alcohol too, but that's all fine, we had lots of furry stuff and lots of time to fill up with things to entertain everyone. Everyone had fun and got along really well and it was the most fun I had at a furmeet.
