I cannot comment on how vigorously the law is enforced in other countries because I am not familiar with the legal environment. In the United States, downloading pirated content will eventually get legal notices sent to your internet service provider, who will threaten to (and legally is required to) disconnect you for repeated piracy. Using copyrighted pictures off the Internet will result in legal threats sent to you as well demanding settlements of hundreds of US dollars per picture, and they will follow through with a lawsuit if you don't pay. Although I have no specific examples of what Microsoft has done, Autodesk and Adobe have sued people who used pirated copies of their software for millions of dollars. People who operate websites offering pirated content have been prosecuted and sent to prison.
Maybe you as an individual can get away with it in your country, but don't assume it is the case all over the world.
Nope, just that Hitler is one notable counterexample. There are plenty more European war criminals.
Don't forget Hideki Tojo too. Not white, but still a light-skinned war criminal.
Vladamir Putin is wanted for crimes against humanity right now. There is a warrant out for his arrest.
And are we just allowing the current situation in Israel to slip our minds voluntarily?
