Respect for the beliefs of others....
.... is a bit of a funny concept in itself. Respect should be shown for people, no doubt- but also for any half baked idea they not only have, but can't justify? Surely not.
Respect for people should be automatic. Their ideas on the other hand have to earn respect the hard way, by standing up for themselves in the cold light of rational criticism. Or even of irrational criticism, for that matter.
No idea or belief merits respect simply because someone holds it. Otherwise we just fall into weak kneed relativism, and have a hard time knowing what to do with the various Pol Pots, Hitlers - and Ayatollahs - whose ideas really merit very little.
