Speaking for myself. First, thinking a Utopia is possible with humans involved is delusional af. Secondly, striving for more or personal freedom and less human suffering is not an unreasonable goal to set. I'm not an enemy to those who practice religion, I am however, an enemy to religious indoctrination and it's ideals and that makes the believers panicky. A Utopia would be boring anyway. How do you get to hell being boring?
