Take a look at the fundraising appeals from some members of Congress as well as those from the offices of some environmental organizations. They appear to share an attitude that if you want to separate a fool from his money, scare the hell out of him. It's more cost-effective to demonize your opponent than to inspire people to your cause. Why persuade by reason when exaggerated and false accusations stir the masses. If your cause is just, your means need have no intrinsic virtue.
Facts are devices and all truth is relative.
No doubt, these solicitations which go to millions of Americans are very effective. But, they have a consequence. Ultimately, they contribute to the partisanship, gridlock, and the utter alienation of the people whom we profess to serve. I do not argue that serious political differences should be papered over. They must be fully aired.
