Here is a great article written by Ben Crenshaw at The Witherspoon Institute

Conservatives are called bigots because those who embrace the new sexual mores are beholden to the new tolerance as a plausibility structure. Postmodern liberals cannot comprehend the idea that one could simultaneously reject a belief and accept the person who holds it.
America is in the midst of a raging national debate on issues surrounding sexuality and gender. If you dare to suggest that gender is determined by sex and is immutable, that same-sex sex acts are immoral, or that marriage is a permanent, exclusive union of husband and wife, then you will be called an intolerant bigot, hater, and homophobe.
Where does the charge of bigotry come from? Is it just a passing fad, a political and social tool for power and control, or do its roots go deeper?
Bigotry is defined as “intolerance toward those who hold different opinions from oneself.” Notice that bigotry is not intolerance toward the opinions or beliefs of persons other than yourself, but intolerance of the other person. Bigotry is not simply disagreeing with what someone else believes; it is an unwillingness to tolerate or accept the person who holds those beliefs.
A little reflection on this definition will reveal that the vast majority of bigotry accusations populating the internet and in public discourse are not legitimate ones. On the contrary, they are the consequence of a mistaken view of tolerance that is itself a product of a warped postmodern epistemology.
