I used to have a Gadsden flag sticker on my car and received many compliments. I bought two dozen to keep in my door pocket and offered them for free to those who have complimented me. Not since Trump has been elected though. For the exact reason that you gave.
Back when I lived in ultra liberal metro Boston it was impossible to have a nice vehicle. I bought my first new car in '85, after I left the area, and had to take a quick trip to a large shopping center when I was back visiting my parents. I hunted for a "safe" parking spot far from any of the entrances and other cars. When I came back 15 minutes later I was rewarded with a fresh ding from the shitbox car that had just parked next to me.
Liberals are like that- no respect for your personal property and if you have something nice, they have to screw with it because after all, it's unfair that you have something that they cant afford.
Come to think about it that's a good theory on WHY liberals love punitive taxes on the rich...
