That was amazing. There were somewhat similar tests on TV over here - like, with a store clerk telling a black person who's just looking at items to leave in a racist conception of thieves, and a woman mistreating her grandfather and such - but apart from mean stares and whispers and shy comments, little happened. The people in this video stood up to the mean person a lot, which was surprisingly nice.
Though coming back to Carmen, seriously, I'd so never do that. I mean, "you look familiar" - "yeah, I'm transgendered"... I don't know about the whole "helping trans people with disclosure" thing, but she's sure going extreme.
PS: Whoa, this commentator sure is annoying. Are all American shows like this?
