From Don:

I saw this vehicle this afternoon while visiting my Mom at the hospital in Greensboro, NC.

The pale yellow bumper sticker reads as follows:

Bumper Stickers - Greensboro NC - Dissent

Somehow I don’t think the owner would view conservative dissent in quite the same light.

It’s also another misattribution, which is common in bumper stickers. That was a statement made about Molly Ivins, not by her. As it anyone cares, anyway.
