Well, the issue is quite simple. If you dislike gays and lesbian for breaking Torah Laws, that's ok. But you must be fair and hate EVERYONE who breaks Torah.
If you just think homosexuals are negative for the society, then it's a problem, b/c noone can tell another person what to do in his private life, unless the reprimand is based on a Divine Law.
The Maccabeans had a great religious zeal, and they named their children Alexander, after Alexander the Great, who was said to be gay and surely was an idolator!!! It seem that ancient Jews didn't care so much about a Gentile's private deeds. Why should YOU care so much?
They only thing about gays that scares me is their activism for gay marriage and adoption. Gay individuals do not trouble me. One gay saved me once from a gang of Nazis
