Do a Google search. Just because you don't follow developments in economics (not saying that you should, necessarily) doesn't mean that there aren't any.

What do you mean "prove the Laffer curve wrong"? It doesn't even apply unless the tax rates are in the 65%-70% range (http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6VBW-3YN9DR5-4&_user=10&_coverDate=12%2F31%2F1995&_rdoc=1&_fmt=high&_orig=gateway&_origin=gateway&_sort=d&_docanchor=&view=c&_acct=C000050221&_version=1&_urlVersion=0&_userid=10&md5=f44231415bc8e9f0881141aedf26e1d6&searchtype=a, among others).

Of course there's a point of diminishing returns. And there's actual empirical evidence to suggest where it is. We're not even close to it. Why is this so hard for you to understand?

Yes, that's all correct. What's worrying is the simplicity and inaccuracy of Medved's arguments. "Actually, the second round of Bush tax cuts in 2003 brought increased revenues – both in actual dollar terms and as a percentage of the GDP (Gross Domestic Product) -- not falling levels of government support. In 2007, six years after Bush began slashing tax rates, revenues rose above 18% of GDP –more than the 60 year post-war average. " Is anyone really naive enough to accept that? I guess if you're inclined to believe it anyway and don't read with a critical mind. "Tax rates were cut and revenues rose so obviously cutting tax rates increases revenues." We should cut taxes to zero so we can bring in infinite revenue and everyone will be...

I don't think there's a lot of day-to-day racism in most parts of America, but there are states in which more than half of whites don't believe that the president is a real citizen. It would be very difficult to deny that there is a racist element to that kookery.

"When the acorn (oops, I mean “census” worker) comes to the door, ask for identification. You will need it for the police report that you will file after your house is broken into. Some of the questions such as “what time do you leave for work?” and “how many hours do you work per day?” can (and will) be used by acorn census workers to “case” your residence and will be seen as an opportunity to take whatever they want to fulfill their sense of “social justice”. I plan on asking for ID, writing everything down, and then telling them to leave (without answering any questions) since I cannot verify their identity."

Dennis and/or the site administrator has a moral responsibility to respond in some way to the mentally disturbed people...

How far Dennis has sunk. As others have mentioned, he's taken to what has to be a deliberate misreading of the opposition. Krugman explicitly said that asking tough questions is fair play, and preventing people from speaking isn't. That's something so obvious that it should be unnecessary to say, but, alas, it is necessary to say to many modern "conservatives" (I consider myself a conservative, but I have nothing in common with these people).
