I am in agreement with you.
Possible T-shirt themes...
"You don't have to be gay"
"Choose a positive life"
"Don't give in"
"He died for all of us"
"Born Human..everything else is a choice"
I bet the list could get pretty long.
Those are excellent suggestions for T-shirts.
"Choose a positive life" is not a good one. I read in a thread in FR about a gay magazine. Well, it turns out that gays classify themselves into "positives" (with HIV) and "negatives". A gay was telling the "negatives" to stop whining "it's so difficult to not get infected"; he was telling "negatives" to get positive in order to just enjoy sex without being worried about the disease.
"Choose a positive life" sounds exactly like this gay was saying.
