I just coined a new term in my head. I'm going to "Ian" you:
Dictionary.com's definition of Combating includes "oppose vigorously," and as I'm opposing the statement itself and not actually intending violent or disruptive confrontation with the person using it, I'll stick to it.
Now I feel like a pretentious ass. Not that I'm calling Ian that, or anything, just how I feel about me doing that.
I like to turn around the "Ignorance of the Law" argument. I could actually pull out the original and full quote to give it the appropriate context and display the perversion of the phrase, but instead I keep it simple. "Ignorance of the law is no excuse. This is a deeply ignorant law, and the people who made it are ignorant of life, liberty and property. Ignorance of the lawmakers is no excuse."
Another notion on slavery compared to taxes is a little numbers game. Prior to the American Civil War (or as I like to call it, the Secession War), an estimated 60% of the Southern states' population were slaves. Looking at that to be approximately 30% of the total population of the USA, they were 100% enslaved. After slavery has been abolished, the average tax rate on people nationwide, which we have no say in, are imposed on us without our consent (except those who passively consent by saying/doing nothing about it), and will be imprisoned while "forfeiting" all we own if we refuse, is 30-40%. That means 100% of the people are now 30-40% enslaved. Slavery never went away, it just became more "fair."
Good discussion so far, by the way.
