I must admit I'm a bit hypocritical because I don't like people swearing around my daughter if it is avoidable, but I do own a few shirts with swear words on them. So kids who can read can pick up the swearing that way.

Most of my shirts aren't that bad just words like "********" (a motorhead shirt) but DP has some that say F*** (Machine Head shirt)! I actually don't really like vulgar t-shirts all that much either, but I'm not going to go telling DP he can't wear his t-shirts in public.
