I definitely think that religious extremism should be fought against. There are cases where religions go from preaching a set of principles and beliefs, to where they are just preaching about hate and violence. That is why I think people should fight against cases where extremism is being taught to the followers.
Religious extremists have minority viewpoints. I respect that. However, while I have to be tolerant of their right to have that viewpoint, I believe that we should do all we can as a society to fight against their attempts to push this world view on others. We all have the right to our own viewpoints, not the right to force them on others.
The time for tolerance for religious extremism has ended. Human rights for minority groups have suffered greatly under religious extremism. People have been seriously harmed by extremism, both physically and mentally. It is important to push and fight extremism from the religous because their beliefs are a threat to freedom everywhere. Religion does not work under democracy, only under authoritarian rule.
In my opinion, Religious extremism should not be tolerated by any means. People of religions like the so called "Religion of peace" Islam, have been killing people almost every. Killing people should never be a reason for religion. If God wants a person to commit a horrible act such as murder, then God should not be followed.
