Weaboo=people who want to be japanese or love that culture
I dont see people who want to be Japanese as a bad thing. You dont need to be born in japan to be japanese either, you just need japanese citizenship.
I see it same way as how Mexican migrants (or any migrants for that matter) want to be American or get american citizenship whether it be for economic reasons or they love the country/culture.
Maybe the problem is the reason these "weaboo's" want to be Japanese that gets people.
Whats your opinion, I actually have no problem with weaboo's, they should be proud of what they like and what they want to be.
Many people love america and want to be American because of Hollywood movies, just like many people love Japan because of Anime (but i must admit, i think these are not good enough reasons to want to change your citizenship)
