Honestly, I rather doubt that most car burglars are even looking at the decals. What they're going to be looking for are cars parked in easily accessible, but not easily visible, places. Dark areas of nighttime parking lots, side lots not visible from the street, some driveways, etc. Their first goal is to not get caught. Their second goal is to find something easily pawned, or sold to a fellow hooligan for drug money. When they're looking at the vehicle, they're probably not going to spend time reading all the bumper stickers; they're going to be peering into the windows to see if there's anything visible and of value inside.

Instead of worrying about what your decals and bumper stickers advertise, pay attention to where you park. Try to choose, at the supermarket for example, parking spots that are under lamp posts and fairly visible from an entrance. If you can, leave at least one parking spot between yourself and other vehicles, to make it harder for a thief to hide in between them while breaking in. Make sure you don't have any easily portable items of obvious value lying on the seats or the floor. If you're parking at home, and have a garage, use it. If it's full of random knick-knacks, maybe it's time for a yard sale. If you don't have a garage, or it's otherwise occupied (by a workshop, another car, etc.), try to park somewhere visible from at least two windows of your house or apartment. Again, if it is an apartment complex, try also to park somewhere visible to your neighbors, or by people entering and exiting the building. Criminals don't like audiences.

Above all, lock your car doors if you have anything of value inside, hidden or otherwise. Many thieves will take "lesser pickings" from an unlocked car than greater from a locked one, as actually breaking into it takes more effort, and they're looking for an "easy score."
