A lot of this strikes me as a complaint about nuance. Yes, a lot of this stuff might not be precisely true for every religious person, but it's widely true for religion in general.
I mean, you mentioned Druidry, so I looked up the number of adherents: about 30,000 in the US (unfortunately, I couldn't find worldwide stats). To put this in perspective, the US territory of Guam has a population of aboyt 130,000... IOW, the US has more than 4 times as many resident Guamanians than it has Druids.
People generally don't bat an eye at making general statements about the US that might not perfectly apply to Guam, and I'm not sure why I should give more regard than this to statements about religion in general that don't perfectly apply to all fringe religions.
