There are often hypocrisies with those that choose to ascend the soap box. Some that come quick to mind are Jon Edwards, Al Gore and Newt Gingrich. Though they may be hypocrites, it doesn't make the topics they champion any less "real". Warrens point about taxing returns not leading to less investment is correct IMO.
It certainly can. Patraeus shagging some chick doesn't affect his judgement on military matters. Al Gore consuming conspicuously certainly taints his judgement on climate matters. Warren Buffet is, at best, manipulating public matters for his own gain. At worst he's a blowhard who doesn't get critical feedback for being a hypocrite. In either case, listening to him is something that should have one's internal BS filter on 11. _XC PS - There is a ton of debate on tax/investment/etc in economics. It's not "settled science."

-sure, but that doesn't make Global Warming less "real". I may know that there is an obesity epidemic and I may even preach that people need to be more health conscious. Then, I may go eat a 10 piece chicken nugget, large fries and a coke. This doesn't make the obesity epidemic any less real just because I'm an idiot. PS. Gore makes me shudder too. Edwards makes me guffaw in amazement and Gingrich makes me chuckle as only a cartoon character can. Buffet I really enjoy listening to. Some great Charlie Rose interviews with Warren.
