The cartoon version is real. The second tranny I ever saw was at an LP convention over 15 years ago.
(Most Freepers have never met a tranny. I've met three since the 1990s. And a co-worker told me about her friend who had tranny surgery. So four trannies have crossed my path over the past 25 years. That's what comes of living in a liberal bastion.)
Again, you are describing libertines not libertarians. Libertarians are not nihilists. There origin is in the old classical liberal part of the UK.
