I'm Ithil and I just wish Hetalia would go away. WWII is not funny, Nazi Germany and Japan at its most genocidal are not "kawaii," and I strongly suspect that it has the ability to consume souls as several of my friends don't just like it, they are either insanely in love with it or feel the same way I do. I have not observed much of a middle ground.
So yes, support real history and the victims of those who defined "evil" for the past 65 years; just say "no" to Hetalia.
