I hate that so damn much. Even extends to physical illnesses, "So I notice you're in a wheelchair. Have you tried GOD?" (not their actual words but what it can basically be summed up to) I can't seem to go anywhere in my chair without someone handing me a panflit for some church (or sneaking it on my chair or in my bag at the back of my chair. I mean, fuck my personal boundires and respect of propery apparently.)
Also get a lot on the more agressive version of this which is "The reason you're sick is because you don't go to church and god is punishing you."
