@glitterbag,
It is not about abortion (I am just using abortion as an counterpoint). It is about bigotry.
Just because someone is absolutely sure he or she is right, doesn't mean it isn't bigotry.
Bigotry isn't about what beliefs you hold, it is about how you treat people who have different beliefs. Whether you can question your own beliefs, or accept people who disagree with you without attacking them personally... these are the things that are important in a discussion about bigotry.
In our current political climate, showing respect for people who disagree with you on issues is rare. The habit is to attack, rather than to question or to understand.
The abortion issue is a good example. The question is at what point a fetus is a human life that should be protected. If you believe that life begins at conception than the issue is the life of the baby. To say that this belief is somehow an attack on women is dishonest, and nasty.... it is an example of deliberately misstating the sincerely held beliefs of people in order to attack personally, rather than to respond to them as human beings.
You can disagree with someone respectfully. You can trust their humanity and the sincerity of their beliefs. You can listen to their points, consider what they are saying, and even admit when they have a valid point. All of these things are helpful in reaching common ground and helping our society move forward.
