The last I checked, we don't live in a Democracy, we live in a Constitutional Republic.
How can the emotions of many be deemed valid enough to pass legislation?
I believe it was Dianne Feinstein who said "The Constitution has no relevance to what we do in the senate. It is up to the courts to decide if what we pass is constitutional." I believe she was responding to Ted Cruz's questions concerning the constitutionality of her proposed gun ban bill.
