If you have "seen little of the words" you consider profane, you've still seen "some (few)" profane words. As I said, such posts are usually reported and deleted. Several Ted Kennedy death threads kept the moderators in overdrive!
Neither metmom nor chm-o-3 stated FR is filled with vulgar hate mongers. They simply pointed out that there is "some" foul language.
I certainly see no reason for FR to be banned as a "hate" site, especially if DU is allowed.
Nope I've never seen the 'F' word here, once or twice the 'S' word, don't ever remember seeing the 'C' word or GD word. If they were ever used and deleted that only makes my point that this language is not tolerated here.
