There's nothing new about this. Witness, for instance, all the early Americans claiming that paying the stamp tax would make them slaves. That was in a time when they knew exactly what slavery looked like. Taxes, as I've mentioned before, can be very useful. I, for instance, like paved roads. But even if you don't like a tax, it's not slavery. Here, I have written for you a list of all the times that it is okay to use the word slave.
