They are libertarian for the most part. The person who responded to you seems to be an (American) libertarian himself so perhaps he’s just trying to distance his ideology from this.

I remember the German politician who had scat fetish/toilet fetish content posted by himself all over the internet

Of course the party he’s in is the FDP (libertarians)

Superscript and subscript

I would say it partially has to do with race (in the sense of skin tone). Depending on where you are in Europe. In very “white” northern countries, just having brown skin can easily get you lumped in with all other people with brown skin, regardless of ethnicity or place of origin. Reactionaries will call you a filthy immigrant all the same, even if you’re born here. But in southern Italy, the natives are often not easily distinguishable from middle easterners or northern Africa anyways, so discrimination is mostly of national origin, language, and overall cultural identity.

But both will discriminate against eastern Europeans.
