listen we just want to speak. We start speaking loud because internally we know that we are wrong. Loudness dos,t mean the righteousness of our thoughts.  That,s why an English Author said

From personalities i mean some people who don,t have religious knowledge but they assume that there is big scholar than them. They play with the religious emotions of the people.  And they some other Muslims as Non-Muslims again disturbing the peace of society.

An other example that we can observe that our political personalities here in Pakistan are so intolerant that don,t want to sit together to talk on national, regional, and international issues. Leaders led their nation by example.   Nation fellow their leaders for guidance.

Lastly i want to conclude with final reason is lack of education is also a major cause of intolerance. Un-Educated people don,t want to listen any one and they thought that their opinion is absolute.

I just want to end with few words that my this opinion is not absolute and you can reject it wholesomely.
