I'm also a bit tired of seeing discussion about semantics popping up within the libertarian movement. If everybody keeps dividing the already small community into many different subsections, you're never going to have a big impact on society.
It's good to have discussion, but I do not see why you'd have to form a completely 'different' group for that. Sometimes it's just better to agree to disagree on some points.
Libertarianism is an individualist philosophy. As long as folks agree on ISO, there’s no problem, in my view. The whole point of anarchism is that we recognize people will never agree on everything, so have basic ground norms relating to property, and beyond that, nobody needs to be “united” or helping “the movement.”
