I don't see what dogma you have noted.
But you're right with the observation "It seems that the site is primarily focused on building strawmen skeptic viewpoints to debunk.", and I have a problem with that as well.
For example the don't bath after eatingdon't bath after eating. My impression is, that user smzs doesn't believe in that advice (his mother does). So you can't convince him from the opposite, but only participate in a mock battle, like catching.
Towards a real believer you could ask back, what the underlying problem is, what evidence he has for his claims. Real questions would come with more resistance than these dummy questions, and with more real stupidity.
But the rules to get out of beta-status somehow force to come up with mock-questions.
