Churchill was a racist - racist to pretty much any non-Anglo-Saxon.
He also participated in the Boer war which set up concentration camps that killed many Boers.
Churchill was also responsible for the debacle that was Gallipolli - instead of attacking at Antalya which could have resulted in far less Entente lives lost.
However Churchill was the right man for the UK for the years 1940 to 1945.
He was a bad peace-time leader but a good war time leader.
he didn’t fight against the Nazis because they were racists but rather because they threatened Britain.
In those days, racism was the norm, and he did not make his career by being a racist, but by being the dashing young son of Lord Randolph Churchill, galloping around in South Africa.
At one point, prior to becoming the PM, he had a chance to meet with Hitler, but he confronted Hitler’s aide about his anti-Jewish racial policies, notwithstanding his success on the economic front, and in the end they called off the meeting.
At the time that he became PM, Britain was already at war with Germany, but Chamberlain had made a hash of it and he was called in to rescue the Conservative party from losing the Government and the war.
As for the Boers, Lord Kitchener put them in concentration camps, not young adventurous journalist Churchill escaping from prison camp and becoming the story.
As for Gallipoli, before committing the Navy to that debacle, he had rebuilt it as Lord High Admiral, and it only became a debacle because the land forces that his naval assault had brought in did not immediately attack. Kitchener again. Great at starving Boer women and children, overrated as a general.
It doesn’t matter why he fought the Nazis. Had he yielded to pressure to surrender, with the Expeditionary Force trapped at Dunkirk and France nearly overrun, that would have been the end. He fought the Nazis, rather do the easy thing.
What if Lincoln was a racist. He fought to keep the country together, and the end result was an end to slavery. But all he had said he would do was contain it from expanding westward. The result was brought about by his being assassinated after winning the war, something which he surely had not wanted.
