Its telling that your example is someone explicitly kept out of the public eye during his life. Basically any account of Turing is from personal friends or his professional work. He was a generally good person and great scientist that helped defeat the nazis, but he’s only celebrated by progressives for his persecution as a gay man.

I struggle to find any major social cause he publicly championed or records of his views on controversial topics. I’d like to be wrong, but it’s easy to not have a mixed record as a private citizen. Nobody was grilling him to free slaves or asking his opinion on systemic injustice.

Einstein is a contemporary comparable. He was a great scientist, opposed the nazis, and by most accounts a decent guy. He was even had to flee his homeland to escape persecution as a jew. Clearly lots of parallels. The main difference being he was an idol in his own day so we have way more first hand accounts.

Turns out he was a socialist with varying views on communism, had shifting support for zionism and wrote rascist shit in his travel diaries. You could probably find a quote like Roosevelt’s and slap it on a picture of him, that doesn’t sum up his life.
