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.
I completely agree to your statement. Nowadays, people have very low tolerance. Tolerance comes with patience. Being patient to understand someone and to listen means also having to tolerate with that person. But not all have low tolerance. Bless those people who has the patience for anybody.
