You have very little faith in your fellow humans. Before laws against those kinds of things, there were other social pressures that kept people in line.
Pressures your rampant Nannyism has all but bred out of our Society, much to our detriment.
As for abortion, you are dead wrong.
It’s a shame we’ve been over this so many times and you still refuse to learn anything.
There is a reason there was a schism in the Libertarian Party after Browne died.
So you accepted the party positions before Browne died in 2006, or before his presidential run of 1996, or 2000 or what?
By the way libertarians of course are pro-abortion, it is part of their platform and their whole reason for existence, showing that there are weak, or dissident libertarians that disagree on abortion doesn't change that.
You keep avoiding and evading the issues.
It boils down to that which you avoid admitting to (except for abortion). Libertarian Party Platform:
Throw open the borders completely; only a rare individual (terrorist, disease carrier etc.) can be kept from freedom of movement through “political boundaries”, eliminate the Border Patrol and INS.
Homosexuals; total freedom in the military, gay marriage, adoption, child custody and everything else.
Abortion; zero restrictions or impediments full 9 months.
Pornography; no restraint, no restrictions.
Drugs; Meth, Heroin, Crack, and anything new that science and marketers can come up with, zero restrictions.
Advertising those drugs, prostitution, and pornography; zero restrictions.
