The only thing Im doubting is whether youre still going to be president by Friday, declared Colbert.

Because what the hell are you talking about?

Its just like D-Day.

Remember, D-Day: two sides, Allies and the Nazis.

There was a lot of violence on both sides.

Do they have any semblance of guilt?

What about the fact that they came charging with clubs in their hands, swinging clubs?

Do they have any problem?

I think they do.

Colbert seized on that remark: First of all, sir, the opposite of alt-right isnt the alt-left.

This week, its Robert E. Lee.

I noticed Stonewall Jackson is coming down.

I wonder, is it George Washington next week and is it Thomas Jefferson the week after?

You really do have to ask yourself, where does it stop?

Colbert took it upon himself to answer: Okay, self, where does it stop?
