No, everything, absolutely everything must be ascertained with a critical eye, backed by evidence. Even the curvature of the earth, which thankfully is relatively easy to prove to yourself. Nevertheless, it does not have special status compared to any other piece of knowledge. You can excuse people for mistakenly believing in falsehoods like flat earth when the wool is being actively pulled over their eyes in a dozen other ways, from religion, political propaganda, corporate lies for profit, and predatory employment practices. Why are shame and insults fair game for flat earth but not Christianity or unquestioning patriotism or support for capitalism? Shame and insults only cause people to dig in their heels deeper. If your goal is to raise the veil of ignorance you are failing. Everyone is ignorant in many ways.
And your point isn't even relevant. Scientific facts and politically charged events aren't even remotely the same when it comes to ascertaining truth value. Never in history has there been a war where only one side spews propaganda.

Do you test it each time someone claims that it's flat? I doubt it.

Where have you been living the last 50 years? Christianity is absolutely fair game, at least in the West (or maybe the Western West? you'll have different reactions in Poland). Best to reach for Islam if you want a religion you're in theory allowed to make fun of but not in practice. But even there, it's not society that punishes it, it's a small number of extremists that the mainstream tolerates for political reasons.
And you're not allowed to criticize capitalism? One of us really must've jumped dimensions recently.

But it's not really the same. There's a difference between "I have no clue how DNA works" and "gravity does not exist and we're just not falling into space because the government has people with invisibility cloaks holding us down".
