Huh, I had to go look this up.

The quotes about black peoples are from his personal diary, but apparently as he radicalised he dropped those views?

I can't find a good source for the Mexican quote, but there are a lot of academic sources I saw. I just don't know them well enough to trust them.

I can't find the sexual perverts quote, but Google sucks especially if it's a translated term so primary sources aren't being counted. He did write some essay about The New Man and this is meant to be a large source of homophobia in Cuba. Apparently the 'Deviation of Nature' part is actually FIdel Castro's word, and he put them to work in camps.

Overall I guess it tracks with some caveats?

Half of these comments like the last one are completely fake and the others are from when he would of also told you he hated socialists before he radicalized and he spent the last half of his life extremely anti-racist.
