@revelette,
The US Supreme Court has held that because of
the Constitutional requirement of EQUAL PROTECTION OF THE LAW,
government is disabled from discriminating even in so trivial
a matter as a few moments of preferential seating on a bus.
If that is true, then how can government discriminate qua
who has its "permission" to defend his or her life from the
predatory violence of animals or of criminals ?
The concept of background checks is conspicuously
and egregiously in violation of EQUAL PROTECTION OF THE LAW.
