Tolerance, now a days is a really hard thing to find. People don't seem to tolerate the existence of other people. Especially people don't tolerate other's beliefs. We have no right to kill someone if they believe in a particular religion, what harm does it to you? Everyone should have a right to live their life peacefully and freely.
Tolerance is the act of allowing something. It is a relative capacity to endure or adapt physiologically to an unfavorable environmental factor. It is an indulgence for beliefs or practices differing from one's own.
