My interest is not in Sarwark's attack. I haven't bothered reading this most recent attack from Sarwark, as I have dealt with him in the past (here, then here); nothing surprises me here. My interest is in Walter's comment regarding "our movement." I have addressed this issue once before, but given the path I have walked since then I feel it is worth addressing again.
I will summarize my earlier comments: left-libertarians have more in common with the left generally than they do with conservative libertarians; conservative libertarians have more in common with other conservatives than they do left-libertarians. In other words, the value we hold in our "libertarianishness" is small relative to the other values we hold.
On what basis would I want to form a movement with abortion-approving, LGBTQ+++ supporting, open-borders, universalist libertarians? On what basis would libertarians who support such issues want to form a movement with me?
