There's obvious cognitive dissonance in being obsessed with art while having utter contempt for the distinct people and culture which gave rise to it. But even in less extreme cases, these "criticisms" leveled at Japan are usually based in a superficial understanding informed by things like battle manga, pornography, and clickbait articles from the 2010s. Moreover the people making them are usually from countries which have worse versions of the same problems (e.g. the "women-only train cars" talking point), yet they feel like they can speak with authority on such matters.
