Well, Finland is next to Sweden which is notorious for taking political correctness to totalitarian levels.

There's definitely a political correctness problem concerning topics like income differences (they're pretty much the lowest anywhere in the first world), third-world immigrants and islam but YMMV. I'm not an expert on history or politics and tend to interact with the world from my comfortable bubble of a strict information diet especially as of late, but as far as I've gathered people are quite patriotic because of our short history as an independent nation. Both Sweden and Russia have historically been an obstacle in that regard and the more nationalist oriented people hold grudges on one level or another because of this reason.

The Finnish-Swedish minority tend to be privileged both in heritage and education and both learning the Swedish language and using it in service professions have been compulsory in Finland for quite some time. For example the Finnish-Swedish have their own quota in med school with easier entrance requirements because of less competition. Naturally this makes less well off people envious. There's significantly more racism against the Russians than the Swedish since Russia is still viewed as a military threat, and polls show this fear is increasing because of late developments in Ukraine and other flexing of Russia's military muscles.

The worst political correctness problems concern third world immigrants and refugees in my opinion, and anyone who brings up problems raised by some of them is very easily labeled a racist and politically crucified. There are problems like letting people in without being able to check their real age i.e. adults pretending to be children, not being able to drive them away when they commit multiple serious crimes, people living on government subsidies with no intention to work ever in their lives etc.
