Don't get me wrong; I know exactly what you mean.

I guess the implication is that people who watch football don't care or are simply to stupid to realize what's going on. On the other hand, it is well known that politicians pass unpopular legislation during major sport events — hoping that nobody will notice. Saying things like "Panem et Circenses" can't be offensive by itself then, can it?

Aside from all that, you lost all your moral high-ground in the last paragraph anyway. It might be true that a lot of these people are offensive, but so are you.
