DragonFly,

First of all, no true Christian is going to hate gays or anyone else.

Secondly, God distinguishes between moral issues and those things are about ceremonial unclean.

The food laws had a practical side definitely, but the primary element is that the Jews lived a "separated" life from the nations around them. They were restricted not only of food, but dress, as well as hair styles.

The food laws have been lifted under Christ. But homosexuality as a moral issue has not changed. Paul stated that those who live like that (in agreement with the OT) are worthy of death. The church has no approval to act as executioner. But God will bring those folks into judgment. Our job is to warn and win them over to the truth.
