Acceptable language?

[sandwedge]

Saturday my son had a rugby match up in Tacoma and as we sat in the stands, there was a family yelling profanity left and right. I mean stuff like, "tackle that Mutha F'er"! Being from the military, I wasn't offended as most were. But when did this become acceptable in youth sports? Finally the 1 and only official came over and told them to knock it off or they would ejected from the stands, which drew a couple of more FUs....
