I’m not arguing by analogy.
If Hitler liked milk does that say anything about the goodness and value of milk? Of course not.
If Hitler accepted the theories of evolution does that say anything about value of the theories of evolution?
Guilt by association.
I know a lot about people just by watching who they associate with, and what they believe. These are not minor issues, and cannot be compared to drinking milk. I like milk, but do not believe in evolution ...
