Those who are attacking Tapscott for trying to maintain civility in the political discourse aren’t going to stop there even with his argument to authority (Ronald Reagan - apparently the last one that the right wing considers their own). That will hardly be sufficient, but the fact is that cap and trade is a disastrous policy that wont do what its proponents claim and will significantly increase costs, creating a drag on the economy when it can least afford it.

You can argue the politics without making it personal. Some people just wont.
