for some reason Donald Trump doesn't go in the category of "people named Donald" in my head. like Tom Cruise, he's not a Tom, or a Thomas, he's always Tom Cruise.
when I hear somebody else's first name is donald, it doesn't make me think of him
Not at this time, but if he were to create such damage that it impacts a generation and unanimously agreed as a villain then at that point the name Donald will be associated with him. Ex: the name Adolf is associated with Adolf Hitler.
