You assume too much. We are talking about bumper stickers for heaven's sake. Let me break it down so that there isn't further confusion:

I think bumper-stickers are a weak form of activism that isn't worth the plastic the things are printed on. There are more effective, courageous, and SMARTER forms of activism.

We have seed vendors facing life sentences and you want to slap a bumper-sticker on your car and call yourself an activist? Please. Wag your finger at someone else.
