Where we seem to differ is that you think every individual should be classified as either a villain or hero, whereas I think the vast majority of people fall in between those two ends of the spectrum. The point of my article was to prove that these men expressed racist sentiments and engaged in racist actions and that they're therefore not heroes; the point wasn't to argue that they're villains. That's an assumption you're projecting based on your black-and-white worldview that each person is either heroic or evil.

Also, there's nothing wrong with pointing out the moral wrongdoings of historical figures. That's healthy and essential to the functioning of any democracy. The more powerful someone is, the more important it is to hold them to the highest standards conceivable, because their actions have consequences for millions of people. A "flaw" (e.g., racism) in a powerful politician has much more negative impact on the world than that same flaw would have in a random person's racist grandma. So we need to be extremely critical of these powerful people instead of heroicizing them.
