Fine. Just stop pretending libertarian (with a small "l") has any relationship to Libertarian (with a large "L').
What Libertarians (with a capital "L") support is clearly written on every Libertarian Party membership card:
"We hold that all individuals have the right to exercise sole dominion over their own lives, and have the right to live in whatever manner they choose, so long as they do not forcibly interfere with the equal right of others to live in whatever manner they choose." (Bolding added for emphasis.)
When you imply that Libertarians (with a capital L) support "absolute and unrestricted liberty" you completely ignore the "...so long as they do not forcibly interfere with the equal right of others to live in whatever manner they choose.
