Rush Limbaugh is a kick to listen to. He has two views that are wrong, however.
One is his irrational dislike of hybrid automobiles. There are lots of arguements against hybrids, but they are mostly irrational and emotional. The facts are that hybrids get good gas mileage, and most owners enjoy owning them. If Rush hates them because they are driven mostly be liberals, that is an unfair guilt by association. Actually, Conservationists, like me, are usually conservative politically in many other ways, but we don't like to waste gas!
The other thing Rush doesn't understand is the effects humans can have on climate change. His logic seems to go like this:
"Can we make it rain?...Well if we can't make it rain it is arrogance to assume we have anything to do with climate change!"
This is confusing climate with weather. It is quite possible for human activity to change climate, and most evidence shows the effect of human activities is an increase in average temperatures worldwide.
Other than that, have at it, Rush!
