“If you think about what it means to say “Taxation Is Theft,” you are endorsing the notion that government has come to you like a thief in the night, taken your money, and left you with nothing in return. Unfortunately, that is not factually, or grammatically true. Yes, the government does take your money by force, but you do get something for your tax money, and, by definition, that is not theft; it is extortion. I will grant the anarchists one thing: “Taxation Is Extortion” doesn’t roll off the tongue the same way “Taxation Is Theft” does, but I’d gladly sacrifice marketing for accuracy,” writes guest author Steven Sadowski.
