Gay pride, why would someone be proud to be a sexual orientation?
"Im proud to be straight" said no straight person ever, you are gay you are gay, its nothing to be proud of, oh and for the record, Pride is one of the 7 deadly sins
Who cares why someone does something, the US constitution guarantees the right for citizens to peacefully demonstrate and express themselves. You have just as much right to hold a straight pride event as those holding a gay pride event.
The events depicted in the op are unamerican and unconstitutional.
