Most Western Christians, it's important to remember, don't take the word of the Bible at face value. Homosexuality being evil is more or less a minor message of the Bible, while Jesus's gospel of brotherly love is a major one and one of the core beliefs of most Christian denominations. Homophobia, even of the particularly patronising "it's not your fault son you can be cured, hate the sin not the sinner" variety, goes against a message of unconditional brotherly love. There are a few tricky ways you can try and work around this contradiction, but they all rely on homosexuality being a choice or an illness, which it's not.
The Bible is fairly consistent on homosexuality being evil FWIW. It's one of the few consistent messages in the Bible. Jesus said only two things on it, and both were fairly incomprehensible. The OT is consistent on it that it is an abomination, and Jesus did say that not a single word of the OT was to be ignored.
