You win "first"

"Mass nouns" are uncountable nouns. "Argument" is not a mass noun. Unless you're just making grammar up as you go along.

Wrong. I never said that. You read that.

Ah yes, sociology and anthropology be damned. We don't need to question anything, or find the reason for anything. Just find the easiest target: "you're stupid, and it's all his fault".

That's a valid question.

Again, no. Why do you keep going back to that?

"If a tree falls in the woods where no one can hear, it still makes a sound."

"Incapable of writing coherent, supported argument, yes."

At last you're coming back to the point. Was it problematic?

So it's okay to suggest he was being racist against one group of people, but not to suggest he was being racist against another?

"you're assuming your lack of knowledge of stereotypes makes you unable to identify racism until someone else identifies those stereotypes."
No.

Neither did I say that.

I did not say that either.

That's your (totally false) presumption. Just because I didn't think, and react, exactly how you did. And I questioned something about everyone's reaction.

Like babies. Nobody is born racist.

For someone complaining about racist caricatures, you sure know a lot of them - down to the finest details.

What made you think I was defending him??

You obviously didn't understand my comment at all.

You're complaining that I don't look at, or have enough knowledge about, racial stereotypes??

My point was that I know enough Jews, and all sorts of international people from just about every race and country, to know that that stereotype doesn't exist in the real world.
