what's the deal with the "weeaboo" hate?

>50% of 4chan is in some way related to japan. this is the best haven for japanophiles i've ever seen. Why the hate?

There will always be reason to hate on weeaboo's. They are the embarrassing wannabes who run round dressed as Naruto. Saying things like "my waifu" weaboo to otaku is like dork to nerd. Being a Japanophile is ok. Being a weeaboo ain't cool.
