Let's use the firearm analogy. I like it. Now, the right to free speech isn't exactly like the right to bear arms, because you can't exercise it without firing it. That being said, you're saying that there are acceptable places to fire the weapon of free speech. I'm saying there are times and places that it is acceptable to fire a gun. One prolly shouldn't fire a gun while drunk on a bus unless your defending your self against a Govt or dangerous crime. Ya might get in trouble. The courts have historically said that one approved firing range is a public university. You disagree with their opinion that public universities are acceptable "firing ranges" for free speech?
I'll play.
Free speech is the Arms or gun. Yes universities are a place that traditionally one can exercize free speech (bear arms). So you can bear arms at College but one must still exercize restraint. There is no right to shoot all willy nilly at blacks without consequences.
