Why do people who dislike faith/religion/spirituality become bitter/negative/wrathful/rude towards those people who do like it?

Because it was prophesied to be so. See: 2 Timothy 3:12, Matthew 24:9, John 15:18, 2 Peter 2:1.

1. It is only here and other places where people of faith/religion talk BS &/or force their beliefs on others. 2.

True spirituality is more about empathy with self and others thus it does not suffer from 1. 3. Have you actually read some of the bitter/negative/wrathful/rude from those of faith/religion aimed towards others.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
