Actually it's not. It's my belief that people should be able to decide amongst themselves how they will live together. Majority rules.
Feh. This is why the Republicans will lose votes from the right-of-center libertarian crowd, whom I think really represent the majority in this country, not Bible thumpers who think it's their job to tell grown adults what they can do in the privacy of their own bedrooms. Unfortunately, some people with way too much free time on their hands obsess over this stuff over other little things like, you know, terrorism and the borders.
Our Constitution 'rules'. People can reasonably regulate the "-- crack house next door, prostitutes walking up and down your sidewalks, and an OTB parlor and bar across the street from where you live --" etc..
-- They cannot enact 'drug war' prohibitions, make 'outlaws' of prostitutes, or ban gambling & drinking. -- Or guns, as you avow.
C'mon, -- can you admit that the 14th's due process clause is violated by writing & enforcing unreasonable 'laws'? - Laws repugnant to the US Constitution?
