They're making the (correct) observation that the two things you call out as things people want to "just enjoy" are also filled to the brim with political messaging. You just don't see it as "political" because you either explicitly, consciously agree with the political messages being conveyed, or because you're blind to them (either because of an implicit, unconscious agreement with the messaging, or because your environment has normalized the message to the point that you don't realize it's political to begin with).
In other words, you say it's a complaint about "leftist messaging being shoved into nonpolitical things," but in reality it's not really being shoved in your face any more than any other type of political messaging, you're just seeing messaging you either haven't normalized yet or disagree with, both of which make it stand out more in your brain (either due to the novelty effect, or the backfire effect, respectively).
Deliberate ignorance, accelerationist "if we let the fascists win it'll totally result in a communist revolution, trust me bro, you definitely won't be one of the thousands whose bones are used for the foundation" idiocy, or actual fascists trying to depress left turnout. Take your pick.
