LOL - It is hilarious watching you Americans get your gun boners.
If a study came out tomorrow that irrefutibly proved that higher gun rates, and the attitude towards guns in the USA causes the higher murder rates (which they both do) you morons would still try to spew out your "GO MURICA, GO GUNS" attitude.
I love firearms, I probably own more than you two nincompoops put together, the only difference is I have a brain capable of figuring out the causation between an insanely armed populace with lax rules, and an incredible high murder rate. (One that rivals Mexico, Honduras, El Salvador, etc., etc., etc.)
GO MURICA. Keep killing yourselves, the rest the world will laugh.
