I've been in fandom in one form or another and I've learned this: I can be kind of sensitive and take things personally when they're about my favorite TV shows/actors/movies/musicians, and I've learned who and where I need to stay away from. There are many many places I do not go because I know they will only piss me off and I don't need that in my life. I used to fight those battles, now I know it's useless, so I just let people go on being stupid and excuse myself from it. I try to surround myself with fans that I like and I enjoy discussing fandom with them. For me, I've found that to be the most sane way to experience fandom. :)
