You are committing what is called a fallacy fallacy, and do not address how they are different
I actually did address the claim by showing how your logic doesn't work with anarchism. But if you would like a direct rebuttal, I'd be happy to provide. Here are the reasons that "taxation is theft" is bullshit propaganda.
You do not have a right to your pre-tax income, or any income for that matter. Private Property is a social contract. The money you are being taxed has no real or implied value except the value created by a single cohesive system that involves the same threat of force to reinforce. If taxation is theft, then money is not property and you don't own that house you bought with it. In fact, you trying to keep me from walking ont it and taking some food would quite literally be theft.
The only way taxation can be theft is if you reject the mercantile system. And if you reject the mercantile system, then the money being taxed cannot be seen as property (and therefore it is still also not theft).
I take it you refer to online piracy?
Yeah. Record labels started taking to call it "theft" when they wanted to ban it. They started teaching people it was theft. They got this big FBI banner on the opening of all VHS tapes.
On one hand you are not taking anything away, you are just copying. But on the other hand, to cite yourself, that is of course an oversimplification.
Thank you for explaining to the audience the exact reason I brought up piracy :)
As you are stealing potential income
So is it theft for me to install a lock on someone's door because I'm stealing another thief's potential income? I'm objecting to this ever-widening definition of theft to "whatever I think of as theft". I recently heard an interesting lie: "words don't have definitions, they have usages". The idea was to counter all these semantic-seeming battles. The problem is that words most certainly do have definitions, and if you oppose what a word means (like theft) that doesn't mean you get to oppose others' meanings of that word automatically.
Taxation is NOT theft. If you think it's wrong, find better reasons to think it's wrong than to use a word with a very clear definition that doesn't include taxation.
