The real difference between left and right here is that our side wants to improve it slowly and carefully through the prescribed means, understanding that there are unintended consequences and perverse interests that are likely to make things worse if one cheats and rushes the process through legal fictions and what not.
This is the reason, the reasoning and the method by which the left can easily find the right to murder, the innocent unborn but not the right to self defense & bear arms.
Our Founders understood the nature of themselves and their fellow mankind far better than we appreciate. Society flexes, waxes & wanes within trends, customs and fads; this is nothing new. What was novel, was the formation of government, impervious to the lust/greed/desires of the electorate, itself.
