It's tough, I'm not religious in the least, but I live in a world where some people around me really believe in that stuff, I try not to be a dick about it. Curt genuinely believes that getting a lot of prayers is like equivalent to getting somebody a lifesaving surgery. I try to view it through this prism: would I do anything I could to help a friend get lifesaving surgery? I would, so I guess that's what he feels he's doing in his way.
I admit as much as I try it's still hard for me to wrap my head around prayer and religion and people believing that, but I do try.
