Why is that "fallacious"? You cited firings as evidence that something wrong happened. I pointed out that firings happen for political reasons and aren't proof of anything. I then pointed out again that the firings held no merit in the lawsuit getting tossed and challenged you to explain why tossing the lawsuit wasn't legally sound. You did not have anything meaningful to say on that question.
I'd say George's biggest obstacle here is that he is, in fact, a racist. He surrounds himself with other racists like his brother, his father, and that awful Frank Taaffe (who ran a white supremacist radio show). George also has made other racist comments in the past.

So yeah, he's racist. Deal with it.
