After this world cup, Argentina is being seen as a unique evil, and it's getting more racist and xenophobic. People don't know a single thing about Argentina but Argentinians are all being painted as racist and zionists, and some Argentinian players being violent is apparently the fault of the entire team or even the whole of Argentina. Argentinians are described as uniquely violent. This was not the response after Zidane's headbutt, or Nigel de Jong's karate kick in 2010. Some people are even calling for banning Argentina from the next football world cup. If I was Argentinian I would not feel safe in Europe. I saw a video of Argentinian fans getting beat up by Spain supporters in Spain after the final. Europeans and North Americans are just projecting their own racism onto Argentina and are using that to excuse being racist to Argentinians.
So if you meet an Argentinian, be extra nice to them. And if you're Argentinian: Te apoyamos
On the day of the final, I saw a group of Argentinians having an Asado in a local park, and when I left the park I saw another Argentinian wearing their jersey, probably going to the Asado, and I told him 'Vamos Argentina'. To which he replied 'Gracias'. It sounded like he was not used to hear this support.
Edit: But I don't deny the racism in Argentina at all. My problem is that Argentina's racism is being used as an excuse by North Americans and Europeans to project their own racism problems onto Argentina and to bet racist against them, also impacting the Argentinians that aren't racist
As a Brazilian, I can tell you that the perception of Argentinians as snobs and racists is very old. It may have exacerbated during the world cup, but during several Libertadores da América games, there were many Argentinians fans calling Brazilian players monkey.
I know, and I should've clarified that Argentina does have a racism problem. My problem is that the hate campaign goes too far and treats all Argentinians as the same
