I am a European student wanting to apply to the US to do a graduate program in Physics. I had tried this before, and I remember most universities wanting to know my RELIGION!
So basically I only know one religious person in my entire life, the absolute overwhelming vast huge insurmountable majority 99.99999% are atheists. But I fear saying that I am an atheist in the application because, well, can it be taboo in some places in the US? I mean, surely universities tend to be more secular than other places and surely there is some tolerance. No-one will discard my application for saying I am atheist. BUT, I am worried about what is most optimal and what is most forthcoming.
Please advise

Thanks americans!
