Possibly we've made the same error, then. Your response hit a bit close to home, for me. But I doubt that whoever-that-guy-is-who-made-that is making fun of you, actually. It's crude, but it picks at these beliefs, specifically:
-Reverence for old ideas over new ones (as "I've been here longer than you...").
-Unwilingness to see the things you believe in actually tested.
Aaand thes are positions that are reasonably common, and at odds with scientific principles, and probably worth being a dick about.
But then, the fact is he's got a character called RELIGION who is completely unlikable and believes vehemently in dragons, and that's totally crass and and it's pretty clear why that would bug you. But I don't think this is truly an attempt to characterise all religious people as that guy. But yeah, my general take from this thing is "whoever made that is kind of a dick but he's got a point", not "haha religion is for jerks."
