So they broke up over a discussion of environmental policy? Sheesh.
Doesn't surprise me in the least. My former roommate is a major environmental whacko liberal. Our phone discussions during the campaign in 2000 over our support for the different candidates got so heated that we had to agree to let the matter drop, but it never stopped him from spouting the "Earth in the Balance" crap Algore was spewing. We haven't spoken since the Battle of Florida.
Environmentalists are the most zealous, and self-righteous of the left-wing coalition. They'll support abominations like abortion, but God Help You! if you want to drill an oilwell in the frozen wasteland of Alaska. It might inconvenience a caribou!
Lucky guy. Imagine if he had married her...
I'd say they broke up because as a true believer she couldn't handle dating someone whose opinions on the subject didn't agree with hers, and he probably couldn't stand dating someone whose thinking was so inflexible and feelings-based. I know I can't stand people who have taken a position but can't explain or defend it in any logical way.
