Is arguing "The west does not just send weapons. Europe also helps Ukraine in other ways" nationalism?

I got banned from "World News @ lemmy.ml" because of “Nationalism”, because I argued that especially Europe does not just send weapons to Ukraine, but does also support Ukraine with the injured, with money and with a perspective after the war… My comment got deleted, too…

Does anyone have an explanation or is the mod just some kind of GPT-2 model with a very special understanding of “Nationalism”?
