Well, someone's brain is pretty limited. No, one can be a Christian and still not be a bigot, and the vast majority of Christians are not bigots. But you SHOULD be upset that bigots are using Christianity as their excuse, and tarnishing the faith in the process. Christ taught the very opposite of what these "Christians" are doing.
What evidence to do you have that "bigots" are cloaking themselves in Christianity?
You do realize the strong majority of practicing Christians and Muslims believe homosexuality is a sin and want nothing to do with it? it doesn't mean they're bigots - it means they want nothing to do with contributing to a sin or endorcing what they believe is a sin.... It's not that difficult to understand... In their mind asking them to bake a wedding cake would be about the same as asking them to sin, and if progressives were tolerant at all they would respect that... So as far as I'm concerned you have ZERO resepct for other individuals values...
