Two specific laws were passed in Britain in the last 25 years outlawing FGM. Yet there has not been one conviction. A report recently pointed out that there may be as many as 100,000 victims. http://blogs.independent.co.uk/2012/05/14/female-genital-mut...
Feminists have remained virtually silent on this matter for the past decade or two. The only person to mount a campaign on it is the novelist Ruth Rendell.
When the female "Equalities Minister" recently appeared on the BBC's premiere news programme defending the status quo (along with a muslim man), it was an array of young muslim women accusing the authorities of racism and sexism in not bringing prosecutions.
It really is an appalling state of affairs. And in the last 20 years, FGM has barely been mentioned by British media. I would guess that the total number of stories in the last decade is no more than 20.
When I've brought the issue up with socialist feminists they claim that it is racist to get involved.
So, I think Dawkins has a point. And from my observations of Dawkins he seems to be far more concerned to offend christians than muslims.
