I don't see why it should be a reason to be "proud". Gay is the way he is rather than something he has chosen but it does not confer some form of superiority on him. If he was a paedeophile though, that definitely *would* be a reason to be "unproud".
Whatever, see if I care.
Well you do seem to care enough to make a point about not caring.
You also manage to put the words 'gay' and 'paedeophile' close together in your comment, which is a glib and common association make by people who at best, are ill-informed. There are so many things one could be 'not proud of' and you picked one likely to cause offense to gay men..
For me, 'gay pride' is a reaction to the predudices of others. I was told, as a kid, I should be ashamed of myself for being gay. I was physically intimidated and attacked, because the physical, sexual love I wanted to experience was different to most. I was bullied at school. My parents were fearful of stigma which would be attached to them for having a gay child. I felt noone I knew approved of me and I was ashamed.
My 'gay pride' comes from mostly getting through all that and becoming a successful human being, and for helping others by campaigning and lobbying for change to make life better for similar poeple. Standing up and saying something helps other people overcome their fears. Tim Cook, is heard around the world, in Kenya, perhaps, where recent regressive laws are resulting in violence and murder of gay men.
