A fascinating analysis of religious tolerance in a liberal, pluralistic society. The author distinguishes between ideological and non-ideological identities and the different ways tolerance interacts with each.
Non-ideological identities include race, gender, sexual orientation, etc. Tolerance here is a matter of acceptance of diversity. It is wrong to criticize a person for these identities. That is bigotry.
Ideological identities include political and religious. Tolerance here actually involved criticism and argument. "We do not demean or degrade the standing or worth of fellow citizens when we reject or even ridicule their political or religious views and doctrines (although how and when we do this is always a matter of ethical judgment and good taste)."
