No, I did not. Mind explaining?

Don was talking about alt.right (obviously a play on alt-right: but probably also the alt-right news group, if there is one). However, the standard acronym expansion for the alt hierarchy on the usenet (it actually stands for alternative) is Anarchists, Lunatics, and Terrorists: partly a running gag and partly because alt.* was (and still is) the wild west of the usenet: a lawless wasteland, with the occasional specks of civilization.

...and even that was too restricted for some people, which is one of the reasons free.* was set up.

For some people, any restriction is too much. It's the 4chan vs 8chan thing.

Go to alt.alien.vampire.flonk.fonk.flonk and ask if they are really aliens and what's a flonk.
