It was brought up in a previous thread, but I wanted to know everyone's opinion about BJJ guys going to TKD, kung fu, etc dojos to challenge the people who train there. Do you find it disrespectful? Would you do it yourself? If you don't train in BJJ how would you feel about it? Personally, I think it'd be fun and would love to try it. There are way too many McDojos around my area and I think by storming I could restore some integrity. Sigh, it'll never happen though.
