Yes, you are. Whatever the word is, does not reflect the equivalent societal view. There is no perfect translation between languages. This is why swearing is rarely a reflection of the actual severity of the word. "Cunt" is considered more heavy in the USA, compared to the UK. The same word, in the same language, has a completely different meaning in the two cultures.
See, here's the problem. Think about the word "war" and compare different cultures and their interpretation of a "warrior" - the Japanese were infamous for their head-strong refusal to surrender in almost any circumstances - requiring two nuclear bombs to finally consider surrender. Meanwhile, Turks surrender so readily and so eagerly that a full third of all of the soldiers in the entire Ottoman Empire deserted during the Gallipoli campaign, mostly without ever seeing combat. It's clear that Japan and Turkey have two extremely different interpretations of "war" despite it being translated into English in the same word.
And yes, I will say, the meaning of the word "eccentric" is massively different in Western Europe - specifically, Britain.
I don't know the word for it, because the concept itself doesn't seem to exist.
It's like - imagine if I said, "this is my dog" - and it was clearly a canine. Then you came along, showed everyone a fish, then said "this is also a dog" - and then followed it up with "Oh my GOD, I can't believe you said that non-white cultures have no concept of a dog? Here's a dog, right here!" - before revealing the fish again.
