There are many similarities between radical anti-God liberals and libertarians.
The effectiveness of libertarians is in advancing left wing social liberalism, not in advancing conservative ideals of limited government.
Drugs and immigration and abortion and the homosexual agenda are easy and immediate politics, while the hard slogging conservative goals of small government and the end of welfare and social programs are made less possible, by the libertarian/liberal efforts and goals.
That’s all true - but doesn’t change the history as it turned out - in fact, it demonstrates the divide in the TP movment.
