I know things are beginning to change a bit on this topic, but one of mine is that you can't just casually enjoy anime. Some people seem to think the moment you accidentally see a dragon ball episode that you suddenly turn into davido kun, or regularly glaze one of your 100 half naked figurines of characters that are obviously not meant to look like adults. There can definitely be weird stuff in some of them, but if you can accept the cultural differences in humor, some of the stories are genuinely great. I don't even watch it much anymore, but it's sad to me that so many people miss out on such great content just because they're a little closed minded.
