The bombing in Oklahoma City has focused renewed attention on the rhetoric that’s been coming from the right and those who cater to angry white men. Right-wing talk show hosts like Rush Limbaugh, Bob Grant, Oliver North, G. Gordon Liddy, Michael Reagan and others take to the air every day with basically the same format: Detail a problem, blame the government or a group and invite invective from like-minded people. Never do most of the radio hosts encourage outright violence, but the extent to which their attitudes may embolden or encourage some extremists has clearly become an issue.
