I love Tosh as well. Did not know he was racist in it, or racist at all.
I don't think he's really racist (and gay, for that matter). He just tells those types of jokes cause they're funny. Louie and tosh.0 are the only comedy shows I watch...
I love Tosh.0. I don't have cable, so I see the clips online or in media classes... but he's a genius. I need to see LOUIE eventually.
