I honestly think it's just a good reason to always qualify your preferences. There are dozens of anime for which, if the conversation turned to that anime specifically, or even a major theme, I'd happily talk about it. But most of it really is complete trash. Honestly you can say that about most media which isn't "Christopher Nolan films."

Also, that's not to say complete trash can't be entertaining or have some marginal value. But anime does have a serious problem with sexualizing children, and that definitely keeps it at arms length for me as a general topic.
