What's curious about the left's current obsession with Timothy McVeigh is that it proves that - despite a frantic search for 15 years - liberals have come across no better evidence of burgeoning "right-wing extremist" violence than a drug-taking, self-described "agnostic" who was thrown out of the Michigan Militia and who proclaimed, "Science is my religion." That sounds more like Bill Maher than Rush Limbaugh.
