> Taxation itself is a form of theft.

Propaganda.

> We never had an income tax in the United States before WW2.

There was an income tax during the American Civil War, but it was temporary. Then Congress passed an income tax in 1894, which was ruled unconstitutional in 1895. The 16th Amendment, which made it constitutional, was ratified in 1913. So your history is as shaky as your moral philosophy.
