Generally speaking, as long as you don’t push any National Pride, you will be included and treated as a normal human being by everyone (barring some absolute nutcases).

E.g. at the University in Bergen, there are multiple long-time professors from countries that are or were heavily contentious and loudly hated as countries by large portions of the Norwegian populace at multiple times in the past 30 years: Russia, Turkiye (murdering kurds), China (don’t get me started), USA (horrific war crimes and torture camps), Israel (the usual), majority muslim countries (blamed for all terrorism in early 2000s). And of course immigrant or exchange students that are getting along fine.

Some places may have problems of course, but in general you can feel confident that it will not be a problem.
