Data is Beautiful

In general the culture is very much 'you do you'. People mind their own business and don't discriminate much. There is some animosity towards immigrants from some neighboring countries, but you would already know if that was your demographic. Occasionally you find some disdain towards English-speaking immigrants, but I would say that's overshadowed by admiration in general.

Overall I'd say the vibe is positive.

The main concern with Argentina isn't discrimination but economic instability, corruption, and high crime rates. Buenos Aires, its capital, is rough. If you are seriously considering it, my suggestion would be pick another province and ideally bring your own work as a freelancer or similar, because making money can be challenging.
