“Willful ignorance” doesn’t have the same sting though. At least to me, because sometimes ignorance is bliss and I choose to stay ignorant on a topic, like e.g. the details of a massacre, to not spiral into doom and gloom.

Calling someone lazy though, in this protestant brained western world, is pretty offensive.

Like some lib going: “wow you tankies are abolutely incoherent” would be a prime target along the lines of “you haven’t enganged with anything I said but instead dismiss it all as ‘incoherent’ because you’re denkfaul”.
