Anyway, way off topic, but I guess I wanted to reassure you that even with the CTD tshirts, or the chess tshirts, or the math team tshirts, no one much seems to have noticed! And frankly, just the fact that you're aware of the potential implications means you are not the kind of "parent of gifted" who will drive everyone crazy!
I agree that no one seems to notice my kiddo's shirts either. He just finished chess camp and got a new t-shirt too. Really, I think that other people are probably similar to me -- I will notice the things I'm interested in. E.g., I was amused to see a coworker in a Joy Division t-shirt the other day, but I am unlikely to notice a country music t-shirt. I will notice a DYS t-shirt, but I will not pay attention to all the sports stuff.
