Sacha Baron Cohen has serious guts:

Disguised in a blond wig and in character as Bruno, a gay Austrian fashion reporter who’s the star of another mockumentary, The Bruno Movie Sasha Baron Cohen marched with haters demonstrators who support Proposition 8 ban on same-sex marriage at a rally across from Los Angeles’ City Hall.

Cohen who starred Borat: Cultural Learnings of America for Make Benefit Glorious Nation of Kazakhstan, enturbulated the Yes on 8 crowd with Bruno’s gayness until reporters and camera crews spotted him. Members of his film crew tried to shield him and “Bruno” was eventually whisked away in a van before he had to encounter real media.

Perez Hilton has some video at his site, but there’s not much to it.

Seriously, Sacha, be careful.  The potential for violence is not only great, but it’s been realized to varying degrees.
