A reminder on free speech.

Since it's been mentioned in the comments, and it is a good commentary, here's the "alt text" associated with the image.

"I can't remember where I heard this, but someone once said that defending a position by citing free speech is sort of the ultimate concession; you're saying that the most compelling thing you can say for your position is that it's not literally illegal to express."

(For those wondering, the "alt text" is a written description of an image that appears as a popup in some browsers when the mouse is placed over an image. It's also used to describe images in non-visual browsers and used for accessibility features, for example to be read to those with vision impairment or blindness.)
