Incorrect. I indicated a dichotomy between a pure libertarian society and everything else. Among everything else, liberty can be ranked by degree. I then pointed out that many colonial powers in Africa afforded a significantly greater degree of liberty than their post-colonial successors.
And you suggested that by measuring liberty "colonial powers win over [...] third world dictatorships," which assumes the false dichotomy that the only option is colonial tyranny or domestic dictatorship. This is an apology for tyranny (or dictatorship, if the tables are turned) and it is unacceptable.
