Even if you agree with its message and accept its controversial statistics (more here and here), there is still plenty to hate this video for. It's implied message is that people who may be offended or critical of the little girls' indignant swearing really have no right to feel that way because of the much bigger gender problems it seeks to address. This type of rationalization seems to me to be a form of the fallacy of relative privation or what is sometimes referred to as the not as bad fallacy. The form of the argument goes something like:
B happened, and is worse then A.
Therefore A is justified.
The obvious problem with this sort of thinking is that the existence of the worse thing does nothing to change the fact that the less bad thing is still bad. Hence the existence of gender inequality or abuse toward women does nothing to change the fact that little girls shouldn't swear and T-Shirt companies shouldn't make vulgar videos which exploit children to push their ideology. I mean any moron should be able to see how completely inappropriate it is to force these young children (the youngest of which was 6) to confront serious adult issues such as rape. I can only hope the backlash FCKH8 receives is enough to keep them from producing future repulsive videos.
