I'm with SBF- the only question I'm asking is if the zoo is public or private? Privately owned business can (I think) ask such things if they have the same rules in writing for all guests. I do also think you should have been refunded.
The issue is not should she let her son wear this shirt- she does. Now we're looking at the legality of asking her family to leave. We can't ask everyone to share our ideals. I don't get why people let their kids be walking advertisements but I wouldn't imply you're somehow lacking or wrong for doing so. And I certainly would support your right to do so in a public place. So maybe we can back off from saying it is ok because YOU find it offensive and look at the issue. Just me .02

). But, IMO, part of allowing your children to use "f-ck" or any other supposedly offensive word is teaching him/her the inherent power of that word. It's teaching that sort of sensitivity (i.e. Grandma doesn't like those words in her house, so we shouldn't use them there) that is so important if you allow your child to "swear". Further, that sensitivity will hopefully lead your child (and maybe you) to question, for example whether it is appropriate to make light of the Chinese tradition of calligraphy. (Personally, I think we are all too careful to not offend anyone, but that's way OT.)
That's the best statement I've heard all day. I may have to steal that for a sig.
