آپ could, آپ know, just ask her not to insult your پسندیدہ عملی حکمت and accept that آپ have different opinions? I'm sorry, but it's nothing worth killing یا hurting anyone over. Although I get why it'd be upsetting.
USE YOUR BRAINS, PEOPLE. THIS IS WHY EVERYONE HATES THE HETALIA FANDOM. QUIT OVERREACTING TO A LITTLE HATE. JESUS FUCKING CHRIST-
Beat her up? Shoot her with a gun? Kill her with the "cruelest method possible"?
It's very clear why the Hetalia fandom is کہا to be one of the worst fandoms of all time - Because many شائقین are either immature children یا have mental issues. The others prove this statement to be true with their answers.
Listen. The girl is allowed to like یا dislike whatever she wants. Hetalia simply isn't her thing. So what? I love Hetalia to bits, but I'm not going to hurt یا harass people who don't like it.
But آپ - the brother - seem to have at least some common sense since آپ can't bring yourself to hurt her. Still, encouraging others to hurt her is equally bad. Even if you're just joking. Someone might actually be crazy enough to hurt her, آپ know.
What I'm trying to say is: You're all acting like 10 سال old children who can't handle that people have different opinions. Get a hold of yourselves and grow up.
