Why Are Most Christians So Closed Minded When It Comes To Other Peoples Beliefs?

SOme are truly accepting, and willing to accept other beliefs, as it says in their bible. Yet others distort the bible to say that they are then only true way to get to be with God, and everyone else goes to hell no matter their righteousness. I cant think of any stronger sin of hubris than that. Explain yourselves, those among you that reject all other religions and beliefs. And save the scripture. That is not an explanation. Think for yourselves for once. And here come the thumbs down from those same ignorant people...LOL One can tell immediately by that unwillingness to think that there are others with different beliefs.
