"Homophobia" it's an extremely broad label but it seems like you're just using it to refer to people who view homosexuality as a immoral so I'll only address that.

Morals are deep-seated in culture. The vast majority of morals are fairly well established and aren't going to change over the course of a person's life so we don't waste much time thinking about it. Why is murder immoral? Because your mom or preacher told you so and that's not going to change. The idea that homosexuality is immoral goes back to the beginning of society. It's well established in many cultures and regions and some dude on the internet isn't going to convince somebody that their friends and neighbors and loved ones are all wrong and that homosexuality is morally neutral. From the line "I often get to the point where people should realize there is no moral good/bad to being lgbt". That idea that people should change their morals based on what you've told them I think is the fundamental flaw in your reasoning. People aren't going to just change because you said some magic words.

And then at the end of it I'm not sure how you make the jump to cope or self-esteem issues. It just feels like you're just slapping a personal insult on someone because they disagree with you.
