Is it still a meme when you make it up?

Bumper stickers I love but would never put on my car:

1. anything anti-Bush
2. Doing my part to piss off the religious right (I actually own this one)
   
3. Get a taste of religion: lick a witch.
4. Affordable health care begins at the breast
5. Tree-hugging hippie pinko leftist liberal -- and I vote!
6. FSM (explanation, for the uninitiated)
7. Reality has a well-known liberal bias
8. Change how you see, not how you look (ok, this one I might actually use)

Bumper stickers I would put on my car without qualms:

1. Pro-child, pro-family, pro-choice
2. Support families, support children, support marriage equality
3. Coexist
4. International Breastfeeding Symbol

Of course it's in a 2-1 proportion. There are always more I can laugh at than I can give bumper space. I've decided it pretty much comes down to whether it's inherently offensive, or anti rather than pro. I have friends I adore who are part of the religious right, who had to use formula, who voted for Bush (really!). I'm perfectly happy to promote my values, but not attack others'.

I still snicker at Can we impeach for a blown job? though.
