(My aside: It’s a salient point, but my reply is, sadly, no. You are dealing with people who truly believe that collateral damage (be it in Vietnam/Iraq/etc., or Newtown) is an acceptable price that must be paid for, in the case of the former, America being #1 (whatever that means), and in the case of the latter, the “Second Amendment” being the most important part of the Constitution. I.e., the Tree of Liberty must occasionally be watered with the blood of six-year-olds.
If 6,000 white male children and young adults were being murdered every year in the U. S, as is the case among African-American males, do you think we would see any hesitation in taking serious actions to restrict the availability of guns?
