Repeat after me student: "It is NOT the govt's job to regulate lives... it is the govt's job to guarantee individual freedoms and rights." What people do with those rights is not the govt's responsibility.
The problem lies in folks thinking someone has to 'fix' these issues... The answer is to let folks who make bad choices suffer the consequences of those choices. You would be amazed at how FAST folks make good choices when they have to suffer the results of bad choices.
IMO the problem is we do not teach the Constitution (and the other founding documents) as they were written and intended. If we did teach them in schools two things would happen:
1) Folks would understand these things, and
2) We would not have such a worthless govt wasting our tax $$$'s.
