You feel that way because you have never felt threatened or afraid to go to a football match like various LGBT people have said. It's easy to claim you want to stop seperating things when you fit into the majority that has never had any issue with society accepting their sexuality. Always easy to diminish the importance or value of something when it doesn't relate to own personal immediate interests. But in the case of minority groups and their acceptance it is important to look past self interest.
How do you know what Ive experienced or from what part of society I am from?
