Everyone that replied to this post was correct & all had a point. As a parent, we should have the right to ok what our children wear & allow them the freedom to make choices.
Nedl, unfortunately & sadly, we do not live in the world you spoke of in your Catholic School days. 
I have 2 adult children. My husband & I were PTO presidents, totally involved & welcomed at their schools back in the mid 80's through the 90's. I now have a teen son & 2 elementary grandchildren. I'm still involved, but when I go to their schools, I know that I need to stand @ the door, push a button & wait for approval to enter. It's disconcerting, but if it keeps my babies safe, I'm all for it.
Nedl, we raised 2 girls first. Girls fight w/ their tongues, & it was a different world then. I've learned boys do things differently! (You made me mad; scuffle; ok, done!). There was a situation that our son was being targeted by a bully in 4th grade. My husband told him to kick his A**.... You can't today! It's a different world.
The pendelum has gone way over the top, I agree! You surf the net more than I do & you see some of the sick things our kids think our funny. They are being desensitized. We have our morals, brains & experience to deal w/ the world. They don't. My 15 yr. old son is still not allowed to watch R rated movies.
That child should NEVER have been given a detention. The remedy should have been to ask him to turn the shirt inside out, parents called & situation explained & this might have gone away w/ communication on both sides. Getting angry doesn't solve it. Communication might?
