I drifted slowly from right-libertarian to a more leftish position: pro-union, pro-social-programs, skeptical of the compatibility of unregulated capitalism with individual freedom. Still no fan of tankies.
This wasn't from anyone sitting down and trying to convince me, though. Part of it was discovering how close right-libertarianism had always been to white-supremacism: some old Ron Paul newsletters were unpleasantly enlightening. Part was seeing people who called themselves "libertarians" line up with the far right to support state violence, especially against black and brown people. And heck, part was from getting richer and seeing how that worked.
I have a lot of sympathy for the frustrations that get young men into right-wing positions and occasionally I try to puncture some of the nonsense they're being fed.
