Humm the way I see it this center piece was in his home not at the school.. It is his home and they can decorate it the way they want too..
I assure you that if you are invited into my home and take offense in the way I decorate my house or how I dress you can turn your happy azz around and walk out the door..
I don't see that it was done to offend...
And if it does then all I can say ya need to grab a set of balls~~

Damn skippy!
