From what I read in the papers the Catholic kids have more worries than a T-Shirt. Also, who says baiting hooks sends you to hell?
In your urge to divert this from SWA to UAL, I don't see the same kind of press for us. Perhaps we either allow more vulgar attire than SWA or our clients are not of the type to wear what would be offensive on SWA. I know which one I think it is and I bet WE don't agree.
