Every gay man over a certain age has stories to tell of prejudice, disdain, contempt, unhappiness, loneliness, of being an outsider, of being shunned and excluded. In my own life, the way I have been treated by straights, by the crackpot religious has scarred me, physically (I am blind in one eye as a result of bullying at school, and I was bullied because I was "effeminate"), and mentally.
But mankind is hateful to mankind. This interesting article tells the story of a man who was imprisoned by the Japanese and forced to endure intolerable things, yet has somehow survived and is happy. He does what I try to do, which is to focus of the good things. Life brings good and bad, joys and woes. This doesn't excuse the vile behaviour of the bigots and the narrow-minded religious fanatics. But it's how we live that matters. And to be happy we must count our blessings, not just all the bad things in our lives.
