Bumper sticker that was so simple that it completely confused me

This morning I saw this on a car:

Regime change begins at home

The car was a bit tattered and beaten up and it was being driven by fairly young drivers. I was sure they were the rebellious sort (ascribing traits based on my inherent biases and internalized preconceptions). Therefore, it was natural for me to worry about what devious plots might be going through their heads as they no doubt schemed to overthrow the dreaded parental authority at home. Perhaps they had already devised a way to create anarchy and chaos, to destroy existent methods of communication, and to replace dictatorial rule with proletarian control.

I was so wrapped up in my spin that it never struck me that the sign was of a political nature until I started writing this post.
