I know some young 'hip' people that hang out in coffee shops and go to churches with names like 'Arise' or some shit, but they're not hipsters, they're just squares latching onto the hipster image.
Contrarianism since all their peers are atheists.
Also Christianity fits pretty nicely in SJW politics.
I also imagine the aesthetic has a bit to do with it.
I mean I guess, but they literally only have the style of dress. Like, they look mildly vintage and the guys wear boots. They're still socially conservative and don't listen to good music or anything. They're not what I call hipsters, they're just dressing and acting in a way that's slightly forward-thinking but generally safe. They're mostly too young to actually be hipsters.
I feel like it's only militant hipsters that are trying too hard, but I guess that's most of them. The hipsters I know have the most edgy views on Christianity to the point where it's saddening.
Take a look at this picture and form your own conclusion, it wont take long
Believe it or not, it all started with those 40k autists and their >muh heresy meme. It quickly moved from nerds and their 40k to /pol/ hipsters and the Catholic church. It's all a big ERP circlejerk.
This sounds very similar to what a friend of mine is going through at the moment.
Pretty standard reaction. Swings and roundabouts.
Atheism becomes cool so 'cool' people become religious. Religion becomes cool, so 'cool' people become atheists.
This cycle goes back centuries.
