How to leave the hetalia fandom?
You leave it like every other fandom. Either by editing other fandoms, talking about another fandom, etc etc. What about the fresh tumblr fandom? I’m not sure since I use twitter and Instagram most of the time. But if you are wandering in twitter/instagram, Genshin Impact and/or MCYT ! It has a less toxic environment than hetalia. Although, MCYT is very sensitive so be advised !!
I’m really sorry for my horrible English but hopes this helped.
