And they heavily share the proselytizing aspect of many religions as well.
I generally doubt that the striking down of religion was a force for good. When we've kept the "group identity generation" only partially in this world and a lot in the next, you can feel all high and mighty knowing that you will go to paradise while the wrong-believers will go to hell, and God will judge everybody.
Now, there's no more God to judge, there's no more "in the afterlife", there's only here and now, and everything becomes an integral part of your identity, from your programming language to your favored comic universe, and it all feels much fiercer. Maybe it's the lack of the after-life where they can be punished, so you need to see them punished in this life.
