That’s a plausible assumption; however, they all occurred when I was parked in places I don’t normally visit. I take it you’ve never had a liberal scream at you or hurl insults at you - things like “bigot”, “Nazi”, “fascist”, etc. - when you offered a viewpoint that countered their dogmatic perspective on anything? I’ve found that liberals are rarely more than a couple talking points deep and don’t appreciate the value of logic.
Furthermore, and being completely honest, I haven’t really cared whether communists/Marxists/progressives/socialists (but I repeat myself) “like” me for a long time. I used to just walk away, shake my head and avoid the discussion, but no longer do that.
I'm in Reno, which is mixed. Walmart is frequent destination, plus libraries, boy's school, etc. In each, I've actually been approached, complimented on the sticker, and asked where I got it.
BTW, the Trump sticker is the only one on the car, a Honda Pilot. Been debating an NRA sticker. Would put and S&W one on but don't see the need to advertise that I am or likely carrying a gun or that there might be one in the car--going to and from range, etc.
I'm spotting a few Trump stickers starting to show up on cars, not many. Definitely more Sanders and have yet to spot a loser Cruz or Clinton sticker. Never once.
