Believers hate atheists cause they challenge certainties believers have about the order of life.
Religion can be so narcissistic that way.

Atheists only position is: let's take time to evaluate the evidence and come to reasonable conclusions about the world we live in. The theist rebuttal is: I don't need evidence, I already know all that's true about this life, death, and the next life. It's such a self-serving narrative. And whenever you attempt to remove people from any self-serving, emotionally charged belief system, you receive a lot of blowback.
Atheists just have to know it's nothing to do with them and everything to do with theists. For example, if they think they can't be moral without a divine rule book, it just shows you their insecurity about their basest human desires and the trouble they have in navigating them. The rest of us don't have that problem.
