Lol apparently you were not on the internet between 2003 and 2009, when hordes of juvenile males went online to “school the world” about atheism.
Point is, it’s not atheism people hate as much as it is the personalities who attempt to champion it.
“The atheists are the smart ones! “ leered Dawkins.
Honestly, the new crop of atheists has, unintentionally , done remarkable harm to the communication of science to those that need it most.
So, people tend to hate ideologues of any kind, and that’s why fundamentalist groups get the same pushback.
Ideologies are obnoxious 🤷🏻♂️
