A gay guy in his late 20s was turned down from a flatshare because on of the flatmates did not want to share with someone who was gay. The person organising it had to send a message to him having to reject him because this guy would not compromise. He was shocked that such attitudes still exist in London.
Welcome to the world. Sorry - it's crap to face rejection if you're white and male and professional. I bet other people have been rejected for being too poor, the wrong religion, female, trans, too old, disabled etc. It must have been an eye opener for you - but yes, discrimination is still alive and kicking. Most people who get rejected from a flatshare don't get to have their story in the paper though.
If people did get to have their story of being rejected for being a member of a minority group in the paper, the papers would be full of such stories.
