I'm not talking about racial differences but cultural ones. You'll naturally approach a certain problem, topic, hobby etc. differently depending on the kind of environment you're evolving in. Just like behaviours can differ from one national fanbase to another, fujos like any other group of fans can act and view their hobbies differently depending on those same parameters, and like I was saying in my previous post, it's very easily observable on a platform like twitter utilized by several fandoms for the same series.
And since we're more or less talking about EH, if you wanna go full autismo you can even make comparisons between these threads with those on 5ch and see which type of shipfags seem sperg the most against it.
Not that I mind all that much since EH being a thing would create a global shitstorm anyway.
