The best advice, IMHO, if you can't find a good clan in the game you're playing- find a group of people who share your views and stick around them. Basically, if you can't FIND a good clan, MAKE one. There are plenty of people out there who'd love to join one just to have fun, but don't because they can't find a clan interested in doing that.
I did that. Best decision I made in Renegade. GDE wasn't concerned with being the best while I was there, it was about fun.
