The self-appointed judges of human freedom don’t get my vote.
I only skimmed this report, but even a cursory examination seems to indicate that the people who wrote it have no idea what freedom might be.
They are indexing for things like freedom to gay-marry, and they don’t emphasize freedom to carry a pistol. The USA and Taiwan rank nearly identically, and the U.K. – land of surveillance cameras – ranks higher than both.
Note that many people are free to carry pistols in the USA, and almost no one is free to carry pistols in Taiwan.
