You should already have heard about the design your own license plate program in Texas. Seems some folks want the Confederate Flag on their plate. Texas says no. The Supremes are going to discuss whether displaying a confederate battle flag on your custom license plate is protected by free speech.
If a state is going to create a license plate program where people can make statements with their license plates, then people should be able to make the statement they want to make. Let's assume for a moment that everyone who wants to display this symbol on their car is a racist. Shouldn't we be thrilled if they want to do so? Here would be a program where racists would voluntarily self-identify to all as a racist (they would even pay extra to do so!) What would be a greater public service?
