I think it's more something along the lines of "bad" people having no afterlife at all and "good" people rejoicing in paradise on earth and hanging out with God forever and ever. I may be grossly oversimplifying.
WAAAAAAAAAAAAAHHHHH!!!! You want to restrict my freedom to fucking oppress people in the name of religious freedom! Your condemnation of bigotry is an assault on my Christian faith!!!!
Recently seen in a comments section about how parents discuss Santa with their kids:
This was much less about being holier-than-thou super-Christians and more about differentiating between The Magical Guy From Up There Who Knows How We Behave And Still Loves Us Anyway to Give Us Good Gifts and well, Jesus. If one's exposed as a lie, the other becomes suspect.
This should really make the poster sit back and reexamine things. If you can't explain the difference between how you "know" God exists and how you know that Santa doesn't, maybe you shouldn't be telling your kid that one of them is unquestionably real and one of them unquestionably isn't.
