When I was younger, I was aggressively homophobic.
Do you still feel that way about gay people?
I just think gay people are scum of the society. They are so disgusting, I can't stand them.
You are welcome to your opinions.  However, you shouldn't make sweeping judgments of people based on something they can't control!
You can't change me. I'm having some fun with it and trying to blow off some steam.
What's fun for you is hurtful to other people, and you shouldn't prioritize your own enjoyment over the well-being of others. Think about how you would feel if people negatively judged you for something you couldn't change about yourself.
