General Motors Corp Vice Chairman Bob Lutz is standing by his statement that global warming is a 'crock.' He says this has nothing at all to do with GM's commitment to environmentally terrific cars. The blogosphere, naturally, has gone apeshit that the guy has an opinion they don't like. What would be interesting to know is if they believe his commitment to environmental cars despite his personal lack of belief in global warming the same way they insist that, say, teachers who are anti-Bush or anti-religion don't let that impact their classroom education.
