That's not my experience. The reasons and motivations are very varied, mostly philosophical and there is a **huge** rejection of the education system. I have been home educating for 16 years and 3 of those I have travelled around the world and met many different nationalities who are educating their own children.

However, I'll concur it seems there are a lot of religious families doing it the US.

This is very true in USA. Every home school parent I have met is Christian or LDS. 

Orthodox Jews send their kids to Jewish day schools where religion is part of the curriculum.

Over 3 Million Americans are Homeschooled

I think most parents who opt for homeschooling want their children to be more grounded in religious/spiritual education (rather than an outright rejection of the education system). So if you don’t move in those circles, you probably don’t want to stick your neck out and choose something different for your child
