At its simplest level, religious tolerance is about allowing others to hold beliefs that run contrary to one's own beliefs. It does not require that opposing beliefs be facilitated, supported, or not contradicted - but it does require that competing beliefs be allowed to exist.Some would dissent from this definition, claiming that religious beliefs should not be criticized, yet this position is untenable and an example of empty-headed political correctness. The mere existence of competing belief-systems is in itself criticism. For example, it's difficult to read the Bible without coming away with the impression that Hindu and Muslim beliefs are utterly wrong, and certainly the basic premise of Islam condemns the heretical Christian claim that Jesus was the son of God.
