Anime - People don't like you when you're into the popular ones.
Video Games - It's everywhere here. If you're into AAA games, you'll never hear the end of it. If you're into Indie games, then you have to be into games like Hollow Knight, Undertale .etc or you just don't know indie.
Metal Music - Fucking hell, you're always going to be snubbed and looked down upon because you're not into Death or Black Metal. Doesn't matter if you're into Iron Maiden or X Nu Metal band here, but you're just not metal until you listen to anything Black/Death. Maybe I don't want to listen to Cookie Monster and Friends.
