That’s how Lefties justify their bigotry against Western Civilization - there must be something genetically wrong with ‘white people’, er, Western Civilization’s ascendency from the 15th Century forward. Rather than taking any lessons from it, Lefties merely want to destroy it all without understanding any of it.
But Twelve Off is right about one thing - this is a side issue from the main subject of this thread. Here’s my opinion regarding gun control in this case - if there is a household which has such an individual with certified social deficiencies as this Adam Lanza - their firearms except for one licensed CCW weapon per individual, should be kept in a secure environment away from the residence where the individual having social deficiencies resides. This addresses the problem and doesn’t affect the vast majority of households with legal firearms.
