Warning: do not read this post if you are offended by the use of a four-letter word beginning with F (hint: it's not "fake").
There's currently a minor storm on Facebook because of a group or groups called Fuck Islam -- there are several with the same name, but this one currently has 769 members. According to The New York Times:
In the month or so since the group was created, the reaction has been building across Facebook. As of the weekend, more than 58,000 Facebook members had joined a group that said that unless the anti-Islam group was removed, "we r quitting Facebook."
Oddly enough, there doesn't seem to be a similar furore about groups such as Fuck Christianity, Fuck Jews, Fuck Israel, and many more.
It's something of a surprise that Facebook allows users to create groups with the F-word in the title, but it could start cleaning the stables by deleting all of them.
