Ah whataboutism, there's no hypocrisy or double standard that it cannot justify. Weren't you taught that whataboutism cannot apply when creating laws? And is actually called discrimination in law. But i must agree it's a convenient tool to prevent population from questioning any and all laws.
When one country invades and the other says "we don't want your books anymore" it's absurd to claim "discrimination". Come on, master of whataboutism, find us some historic analogy. Like Russian imports of German books during WWII.
If your logic leads you to the following conclusion, think it's safe to say that you're on the wrong side of the argument:
Masha and the Bear = brainwashing children, needs to be censored, require exceptions to import
Mein kampf = totally fine for unlimited circulation without age restriction
That's your conclusion, not sure why you're ascribing that to me. I'm sure there are many bad books issued in countries that Ukraine has good relationships with. I never argued otherwise. It's a tangent that doesn't mean anything in the context of restricting book imports from a country they're at war with.
Certainly the whole argument is ridiculous. Is like asking Israel to make Mein Kampf compulsory reading at school or making Carl Marx a compulsory reading at Texans schools. They somehow keep on insisting that Ukraine should actually be praising and chanting about the main language of the state that is trying to annihilate them. Senseless at all point.
