I don't abuse anyone, I may not like what they believe, but people are not their beliefs, as we are not what we wear, if I don't like your tie, that doesn't mean I don't like you.
Your entitled to like whatever you wish.
Beliefs are harmless... until being taken as reality.
Once you begin to consider your beliefs as more important than humans well being... That the point to stop.
It can be as far as I'm concerned convincing women they must cover their entire body.
It can be convincing children that they are evil.
It can be mutilating another.
It can be preventing woman from singing.
It can be treated others as lesser than you because they don't share same beliefs..
But yes... Beliefs in general a a great thing and obviously very useful.
But be aware of what your beliefs are causing to others.
