If I start espousing the great ideas of economist Karl Marx in a long comment I will forgive you for assuming that I may be a bit of a Marxist unless my comment has clear caveats to the contrary.
They're free to prove me wrong by saying that they're in favour of sales tax or income tax or capital gains tax. That would prove to me that they're just taking the idea that "land value tax is good" without buying into Georgeism as a whole. But I'm confident we'll never see such a comment.
