When he sees an obunghole or similar bumper sticker some guy I know either wants to:
a) Answer it with a conservative one
b) Road rage hit the cretin, jerk him / her out of the car and smash their face in
c) Follow them and use his trusty section of 1 1/4” pipe on their car
I don’t bumper sticker for fear of some lefty doing these things to me and they are not nearly as restrained as I am. Not at all.
Someone may have:
a) caved car doors in with a good swift but very firm backward kick as they surreptitiously bent over to reach for something in the car through their open door
b) seriously keyed more than one very expensive vehicle
c) on a very dark night backed into a very large mercedes, driven by some puke, in a parking lot with a very large and heavy gooseneck flatbed, oops.
Your friend is an asshole and should go to jail for his behavior. It’s not funny.
