Religious toleration is the condition of accepting/ permitting others' religious beliefs and practices which contradict/disagree with one's own view/practice.
Religious tolerance is different from respecting the religion itself. It is agreeing that the other person has the right to hold on to his/her belief. It is respecting the right of others to hold their beliefs. If there was respect for all religions it wouldn't make us progress. Progress comes from questioning a certain belief and evolving it overtime. Criticizing/reforming a mainstream belief is the same-thing as disrespecting the religion. But this criticism lets us evolve and progress overtime.
I for one, respect, and accept the right of others to hold on to different beliefs which may contradict my own. But I may not respect the religion/belief itself.
For example I do not respect the belief called Wahabism, but I do respect the right of people to hold on to their beliefs (if they do not mean any harm to others). For me, Wahabism, is sexist, backward and primitive and these people have strayed away from what they believe as a scripture in my opinion. I'm just expressing my opinion.
Another example is that while I do not respect creationism (the belief itself), I do respect creationists' rights to believe and hold on to that belief, and also criticize my own belief of evolution. I would not get violent if they criticize my beliefs and it should be that way. There is no point in being violent. It is a reflection of uncivilized, devolved behavior in my opinion.
