Ed Begley Jr.'s electric SUV and tree-hugger haters

After I checked out a Yahoo video regarding Ed Begley's electric SUV, I thought I'd check out the comments. I was surprised at the negativity of some of the posts. Moreover, I was shocked by the amount of hate some have towards "tree-huggers". I guess it's probably no different than the hate some treehuggers have towards 'gas-guzzlers'.

Still, particularly since 9/11, isn't foreign oil dependency a national security issue? Consequently, isn't gas-guzzling far more than a tree-hugger issue?

What do 'gas-guzzlers' care about, if they don't care about global warming, pollution or national security?
