Yeah, controversy is a pretty thin line to walk. I find that people who swear or offend others just for the sake of it extremely annoying. For example, I just discovered that Sarah Silverman - who I’ve never heard of before Wreck-It-Ralph and whose character I absolutely adored - drops a lot of expletives on her Youtube videos and Facebook page, oftentimes just for the heck of it (although her recent political video on voting barriers is compellingly-presented).
I find those who are rude but have something important to say are those whom I admire more. Sacha Baron Cohen, for example, in Borat, was excellent because he played a character who revealed other people’s insecurities and prejudices. And I greatly admired him in that outing. Bruno, on the other hand, is such a repulsive character in his movie (sexually harrassing people like no sane gay person would), that I lost all empathy for him. I have yet to see The Ali G Show movie and The Dictator, but I’ve seen a few of his Ali G TV show episodes, which were kinda okay.
‘Clean’ funny guys like Gabriel Iglesias and Russell Peters are the ones who get the most laughs out of me, although a few ruder Eddie Murphy and Dave Chappelle stand-ups got me chuckling too.
