Churchill was a significant leadership icon (WWII). He was also a poor leader (WWI). He held racist views. He was also very witty. People are complex, and one perspective is not enough to do a person justice.
Case in point: many people around the world think of Mahatma Ghandi as a very positive cultural and political icon. Except students in the biggest university in my country, who protested [0] to pull down his statue over his racist views.

This is a completely absurd position. The Nazis carried out a deliberate extermination programme, murdering millions their own citizens.
The argument Churchill is great, is the western version of history, a majority of of the world do not agree with that ridiculous assessment, because of the internet western version of history is increasingly getting challenged and I understand it is making you uncomfortable.
