Not scorn CS, but I'd be a little less cynical if the Russian feminists weren't so strikingly beautiful and well made-up in the photos as they get arrested. Doesn't it all seem rather staged ?
Maybe it's all done deliberately post-modern ironic counter-something-or-other, but the group makes assertions that simply aren't true. This for example from the Guardian's interview with FEMEN spokesperson Alexandra Shevchenko :

"No one is talking about FGM in England," she said. "People assume it is too violent and extreme to exist here, that it only happens in Africa and the Middle East, but the UK has some of the highest levels in the west."

In fact women in the UK have campaigned to bring the issue to the world's attention for many years British journalist Jill Tweedie wrote about it in The Guardian as far back as 1976.

"The Foundation for Women's Health, Research and Development (FORWARD) is a British charity, founded in 1983 by Efua Dorkenoo, that provides support for women affected by female genital mutilation (FGM). It also works to end the practice, and campaigns against child/forced marriage. The organization runs several programmes in the UK and in East and West Africa.[1]According to FORWARD, there are around 100,000 women in the UK who have experienced FGM."
