I think all websites should just ban together and direct IE users to a landing page with download links of the other 3 "superior" browsers or if they must use IE they can download Chrome Plus that lets you open IE tabs. Then on the bottom of the landing page they have a choice of proceeding anyway, with caution of course. If people just saw side-by-side comparisons of how CSS renders in IE and the rest of the conforming browsers people would switch in a heartbeat.
