Are you under the impression that religion is harmless fun? Read a history book. Even in modern developed countries, people who turn to religion out of desperation often end up seriously hurt. A huge mainstream cult is still a cult.

There are better arguments that could be posted against why you should turn to Jesus, but I'm not ashamed to downvote the original comment. It's not good advice.

I wonder... if I'd posted a comment saying "Get involved with transhumanism" or "sign up for cryonics", and someone had posted a sarcastic reply saying "Where's the science?" (not that this isn't a perfectly legitimate question with I-should-hope legitimate answers), would you be working so hard to defend me?
