Nope, I meant compare amount signed up to the amount of atheists (raw numbers). That doesn't tell you whether religion is a factor in avoiding cryonics, but it does tell you whether religion is the only thing keeping everybody from signing up for cryonics. Since by far the majority of atheists are not signed up for cryonics, it's pretty clear that religion isn't what's stopping people.
ETA: Okay, Vladimir_Nesov (below) has convinced me I wasn't considering the same question.

That's silly. Too few people know of the idea, and it's too hard to persuade any given person. The question wasn't about absolute difficulty of getting the argument through, but on the relative effect of being religious on the ability of a person to accept the procedure.
My girlfriend/SO's grandfather died last night, running on a treadmill when his heart gave out.
He wasn't signed up for cryonics, of course. She tried to convince him, and I tried myself a little the one time I met her grandparents.
"This didn't have to happen. Fucking religion."
That's what my girlfriend said.
I asked her if I could share that with you, and she said yes.
Just so that we're clear that all the wonderful emotional benefits of self-delusion come with a price, and the price isn't just to you.
