Thank you for your support! Disabling comments because I don't want any more arguing to go on. This stamp is worded pretty childishly, so just to clear things up, I'm not trying to say that Hetalia is above critique-- my point is that there's really no need for people who dislike it to spew out the vicious hatred that I've seen. Please keep in mind that Hetalia is a comedy, and if you take it seriously, you're just making yourself look silly!
A good point made by a commenter is that Himaruya's interpretation is based on Japanese stereotypes of other countries. If you don't understand why such-and-such acts in such a way, it may be because whilst it's not a common Western/American/whatever interpretation of said country, it may be a commonly held stereotype amongst the Japanese.
Himaruya can't please everyone, so, let's all try to be reasonable and just get along!
