So, I flew to S.F. from L.A. on Saturday evening and went to Castro on Saturday night, which went kinda well. Then the next day, Sunday was Gay/Lesbian Pride. It was a nice sunny day.

But can anyone tell me,
WHAT'S THE DAMN PURPOSE OF GIRLS TAKING OFF THEIR SHIRTS??? And the guys without bottoms? What is message people are trying to give?

I'm not hating on anyone, I just want to see if I can understand what the purpose behind that is. Can anyone tell me please..... Thank you.
