when I say he endorsed Trump, I am saying that he supported or approved something he did

Then you are misinformed about what it means to endorse someone. Or just intentionally twisting the definition to allow for ragebait. Contexts and learning what words are used in them is kind of important. Maybe you ought to learn that sometime.

I don't give a flying fuck if Trump ever made some recipe

They didn't ask if you cared about a recipe. You're tossing aside the point of their comment and getting on your pedestal to rant.

I really hate beating this dead horse, but it's saying Hitler actually did make some good art pieces, so we should ignore the fact that he was the executor of a grand scale war

Saying "Hitler made good art pieces" would also not be an endorsement.
