Christian couple told they can't adopt due to their views on homosexuality.

They aren't comparable to racism. Your race you're born with. You're not born a feminist. You're born an atheist but beliefs can change, you can't change your race. Race is a fixed part of a person that is very close to them and cannot be changed, to mock it, belittle it, ridicule it or attack it in anyway is the worst form of all bigotries. Homophobia is probably second worst because it attacks sexuality which is also very close to a person, although not quite as close as race because it's not necessarily purely genetic.
