From Webster ...
"bigot" = "a person who holds blindly and intolerantly to a particular creed, opinion, etc."
Is a person who rejects homosexuality and those who practice it a bigot?
Well the word "blindly" is completely subjective and totally meaningless in the context of this purported definition and the "etc" at the end covers a lot of ground and would certainly include behavior or teaching. So, is being intolerant of sin a virtue? Jesus said, "I have this against you, you tolerate that woman Jezebel, who calls herself a prophetess and is teaching and seducing my servants to practice sexual immorality..." Jesus apparently didn't tolerate sinful teaching or behavior either so the aphorism stands like concrete. If you want to condone perversion that's your right. Don't expect Christians to do so however.
