The Constitution is a working compromise — and part of a delicate balance — for governing a country. The Constitution does not dictate what should and shouldn’t be thought, nor does it tell us what is right and moral. The Constitution does not restrict the boundaries of a conversation, or suddenly declare an idea off limits. The Constitution does not tell us a mass shooting must happen.
“But the Constitution!” is not an argument. It is at best an appeal to authority — a logical fallacy. It is a rhetorical strategy that has been proven wanting before (see: American slavery).
And, as the right to bear arms implicitly attests, the Constitution can be amended.
