A bigot is someone who treats someone else with disrespect. Saying you don't understand something, rather than throwing rocks, is a sign of respect. Discussions are better than fight-fight-fight (though sometimes it's hard to tell the difference :-)
I guess my perspective is a bit different because I know what it's like to have a fundy mind-set (after all, I was one), and I know that most of the people aren't monsters. They just believe what they've been, and I do occasionally miss the certainty) taught by people they respect.
People don't (generally) seek a religion because they want to lord it over others. They just want to do what's right. The problem arises when they classify people who don't think like they do as sinners, forgetting "for all have sinned, and fall short of the glory of god."
