It is a bit of a misconception to say that all Christians are homophobes. I'm Christian, and I surround myself with gay, lesbian, bisexual, and every other type of person there is.
And some people even take a different approach to being against homosexuality. Like some people at my church. They insist on being loving (as they should), but to rebuke people who are homosexual, they basically say, 'We still love you, but we want you to change who you are.' Or that's the basic gist. It's sort of the passive-aggressive disapproval.
Sorry, I'm not sure if that really answers your question much.
