If the federal government were a mere service provider, the idea that shirking taxes is morally wrong might have some weight.
The reality is that the Federal government is an active, rapidly advancing enemy of individual liberty, intent on destroying our civilization, and reducing us to dependence upon it.
And it does that, in part, through the use of funds gained through tax revenue. Of course, even without that revenue, government would borrow, print or steal whatever it needed, but any citizen who keeps what's rightfully his, and thus deprives the Federal leviathan of it, is a hero.
Gaming the system and tax cheats as heroes...
