while also saying andalusians/galicians are lazy, uncivilized untermenschen and how catalan culture is inherently superior. They resent having to actually share a country with the latter, but not the former.

That's completely false. After living for all my life in Catalonia I have never seen anybody saying such things about Andalusians or Galicians. Are you aware that millions of Andalusians emigrated to Catalonia and that now many of them do support independence? We already share Catalonia with lots of Andalusians. It doesn't make any sense what you are saying here.

Also, we are genetically closer to the swiss than to the vile, inferior castilians and spaniards are literally animals.

None of those links say that
