If I remember correctly it was in the late 60's that being Gay was decriminalised. Since then there has been a steady increase in the number of Gay Pride type events taking place and getting more and more publicity. During that time I can't say I have been aware of many, if any Heterosexual/Straight events of that type.
Could it be that the average Straight person is happy in their skin and does not feel the need to prove anything, and the average Gay person feels a need to justify their way of life and to prove something to Society as a whole?
being gay does not mean you have to justify anything to anyone.
straight people do not have to fight for the right to be treated without discrimination, unfortunately gay people do
i see gay pride events as a change to say im gay and im happy with that and im thankful i live in a democracy where people can be themselves. Its not all great there are still some people about who can't focus on anything other than the "sex" part of people's sexuality but things are changing for the better, slowly but surely
It is a chance to proclaim that your mind attracts you to the wrong sex, that you are going to celebrate it conspicuously to others whether they are afflicted by the same issue or not. These events just seems a fairly weird thing to want to do. I don't suppose they are anything to be concerned of though, rather sad really.
Well to get a valid answer to that, you'd have to ask a lot of gay people. My take on it from a non gay perspective is that its not about how gay people feel so much as their challenging the feelings and opinions of straight people in much the same way that any other public demonstrations are.
I expect even when it was decriminalised, it was still seen as something to be ashamed of and people were still treated badly because of it. They still often are. Until attitudes catch up with the 21st century, there will still be marches, i expect.
'why do straight people care what we get up to in the privacy of the bedroom' they say and 10 minutes later they're dancing down the bloody high-street in a mankini.
