Ultimately we're discussing assuming someone is a racist because they said something negative about a person of a different race. That assumption is also a racial stereotype.
The dickishness/meanness of singling someone out by name in a public article on the Internet, which is what the comment here was primarily about.
And then the second level, which the commenter deliberately downplayed as a minor second point (but people here jumped on it...) that said person is a minority, so it makes one extra-suspicious about motives.
So I'm not sure where you got this "acting like race is about everything" point, because that wasn't in the comment.
Given it's an unusual situation, people are reflecting on what makes this allegedly incompetent VP different from other incompetent VPs who aren't called out like this?
