Telling a homosexual that their sexual ways are sinful is not hate, it is trying to say to them that they are doing wrong...
You're right, that's not hate. It is fine for you to share your beliefs with a homosexual.
What is wrong is to not allow homosexuals to have the same freedoms you have. You are allowed to legally marry the one you love. So should they. It doesn't matter if you think it's wrong. It's not hurting you so it's not your business.
You would not like to be bullied. Neither do they. I don't know if you bully homosexuals or not. Although I do feel like you're bullying me a little in this thread. I don't mind. I'm secure in who I am. But sometimes homosexual boys are bullied by their peers to the point of committing suicide. That is hatred plain and simple.
