I guess flame wars are unavoidable; people get set in their ways and things invariably get heated.
I do think it would be a shame to avoid C&C for a dislike of the fans though, because I really do think it can be a lot of fun, and rules lite enough to be attractive in getting newbees into the hobby.
I know that my wife was really frustrated trying to get into 3.5, but found C&C a snap!
...so I get to play more.
Although I do enjoy other rpgs: Alternity, Star Frontiers, AD&D (which I grew up on), D20 (at low levels), Sengoku, etc.
It's strange really, I'm normally cool-headed, but hearing that C&C fans are horrible really stung, especially after I've met so many that are great, welcoming people.
And yes, Treebore's one of them...one who I game with frequently, who has opened up his family to the online community, and who has made me feel welcome in all of his games.
