The flat tax bit actually came up because a high school dropout marine blue collar worker turned libertarian who according to his Facebook is running for Congress weighed in on a min wage thread with how the country is going to hell because the rich are taxed too much and a 20% flat tax would fix everything and we should end all government regulation, get rid of the minimum wage entirely, end all entitlements, require proof that you can pay before a hospital will treat you, impeach Obama, require military service, Reagan was the greatest President of all time, and so on. He frequently links things from ijreview.com and mrconservative.com with gems like "Obama is going to change the law to give himself a third term" or how Obamacare violates the constitution and the usual TeaTard horseshit. Pointing out that we've had the lowest upper tax rate since the great depression for 30 years now and the country, in his own words, is "going to shit" does not, of course, sway his argument.
Basically, he is a poster child slack-jawed retard Tea Party dream voter. He's the kind of person that you wish was parody. A poorly educated yet highly opinionated political activist who campaigns against his own self interest so the rich can get richer and the rest of us can go poor making products that kill us. Someone with actual wealth would laugh themselves silly at this guy.
Probably my favorite line from him though was the bit about how experts and economists and such don't know anything because "common sense" says so and so is *obviously* right. So if you link any actual study, fact, or statistic, his rebuttal is "well, common sense says that is wrong." Every other thing he said was common sense this, common sense that. I wasn't even arguing with the guy because I smelled libertard right from the start but he kept injecting his stupid into what was mostly a half-serious debate between friends (once my friend understood that Obama wasn't actually calling for a $15 min wage)
That wasn't you was it, Merlin?
