My argument here is that when the term 'libertarian' was created it was specifically used by leftists to describe a leftist political ideology and the only reason it is not still associated with leftist politics is because right-wing conservatives very specifically and intentionally "stole" the term in the middle of the 20th century.

Further, in the right-wing context, 'libertarianism" is synonymous with classical liberalism and conservatism. The idea that right-wing libertarians embrace the ideology of personal liberty is just plain horseshit. They embrace personal liberty for one person and one person only: themself. They want 0 personal liberty for anyone other than themself, and if you tell them they are not allowed to restrict the liberties of others, they take that as an attack on their personal liberty. Modern right-wing libertarian political "philosophy" is no more developed than the political ideology of a toddler.

I don't have any personal attachment or desire for myself or other leftists to use the term libertarian. The petulant children can have it.
