Never stop projecting, do you? Where did the post tell anyone else how to live?
How about the title of your OP. You are saying that me, a non-traditional group (at least now. 100 years ago we were the norm) have no right to like the things that I do, and further, you then claimed that it is a mental illness to care about them. That's a progressive tactic you know. Classify those they don't like as mentally ill so you can then murder them.
Typical behavior for you types.
