I don't care much for journalists anyhow. The profession has gotten a sleazy rep over the years, at least as regarded by non-journalists.
The rules of engagement have changed...and pretty much anything goes, unfortunately.
I believe Grun's ire is directed at journalists, and especially yankee liberal ones, with no discrimination of race, color, creed, religion, or national origin.

As far as whether someone is racist or not, it depends on how they treat people. Look at Archie Bunker. Was he a racist? I think not. Though he did stereotype, which is a normal thing and everyone does it.
Anyway, that's all I have to say about that. Carry on.
