Actually, it is perfectly logical to assume that my "ideas and opinions" are not constrained within specific categories determine by a only few of variables, reminiscent of the personality or sex quizzes found in Cleo or Cosmo.

And just for the record, it is naive, not to mention dangerous, to think that all libertarians share the same views concerning taxation.
Do you think David Nolan, the founder of the U.S. Libertarian Party, is a social liberal (?), considering he believes that not all taxes are deleterious, and is actually in favor of land tax?
What about the geolibertarian community as a whole, which believe that all natural resources should be taxed? Are they not libertarians?
Let's not forget the green libertarians, whose wants corporations to be taxed based on their impact to the ecosystem - consumption of natural resources, pollution, usage of public utilities, etc.
Even Ron Paul, flagbearer of the anti-taxation paleolibertarian movement and mouthpiece of Lew Rockwell, is supportive of excise, consumption and national sales taxes.

Labels are for census takers and political bodies. There exists no hard lines in the sand, only a wildly diverging and fluid spectrum.
Take a look at a variation of the Vosem Chart below, derived from the Pournelle chart.
As soon as you begin to realize the complex spectrum of beliefs that we could potentially inhabit, consider that the chart are also limited, only capturing a facet of our thinking.
And then, compared the ideologies of political parties from different geographic regions. For instance, the leftist ideology as defined in American politics inhabits a remarkably similar spectrum as those of center-right Europe.
