Why Do Theists Hate Each Other's Guts?

 i am not sure where you get the idea that religion hates all other religions.

As usual, you don't seem to be sure about anything.

However, my assertion is not an idea but a fact according to what religions say about each other and what is still going on around the world. Each religion, bar none, emphatically assert that they are the only pathway to an afterlife in paradise and not only are there religious wars raging in the Middle East, Africa and Asia but denominations of Christianity, for example, hate each others' guts. Go to Northern Ireland and see how you get along there if you happen to walk into a protestant pub and shout out, "Three cheers for the Pope". You will end up wearing three chairs around your head, if you're lucky.
