From the mid to late 2000s on the internet in general and this forum in particular, there was a sizable contingent of "fuck religion, flying spaghetti monster, i believe in science bro" types who would dominate any talk of religion, evolution, etc. It seems that's all but disappeared and those people have morphed into alt right, anti-SJW warriors who've found common cause, or at least a cold peace, with right wing religionists to take on the wacko left.
I think it comes down to the fact that we (atheists) won. When I was growing up, it was hard to find someone around me who was NOT religious. Now it's hard to find any one that is.
Fighting against religion is on par with fighting people who think the earth is flat or that dinosaurs never existed. You can do it for jokes, but the fight has been won.
