Homosexuality

Apparently me politely stating in a public place that I believe homosexuality is immoral and unethical and the fact the most religions oppose it is "forcing my beliefs on others". Yet homosexuals doing things like kissing in public (I don't think it's okay for anyone to kiss in public), telling people to accept homosexuality or be labeled a "homophobe", adopting kids and brainwashing them into becoming homosexuals, and having LGBT pride marches isn't forcing beliefs.

``If we talk about Nature, saying that bestiality is ok, they that mean that a man can have sex with a female dog and have Human puppies''

wrong, sex doesn't necessarily have anything to do with the ability to reproduce.
Do you go around telling men or women who are infertile that they aren't allowed to have sex?
