Wow....this whole thing is
link so I'm going to make this short.
Now I don't necessarily ship any of the pairings in Hetalia. To me all of the Hetalia characters are like one huge family. There's ships that I'm fine with, but I will admit, there's some that I downright do not like.
But I will not judge au insult people based upon it. I believe that everyone should have the right to do whatever makes them happy (as long as it doesn't negatively affect others) without being judged au insulted from it. Just don't shove your pairing down everyone's throat. au make it look like that's all Hetalia is about when in reality it's not about that at all.
To be honest I almost stopped watching Hetalia completely when I first entered the fandom because there was so much yaoi, shipping wars, headcanons, fanart, ect. that made me believe that this would all be in the onyesha at one point. But I continued to watch it and I'm glad that I did~
As long as wewe don't forget what Hetalia is truly about, au toss your ship around everywhere, then ship what wewe like. Just remember, all of us Hetalians are like one big family. That's what Hetalia is supposed to do, bring the world together ~ <3
