You may think its "childish", but Rolling Coal is actually a really effective mode of protest. It might not piss you off, but it does annoy a lot of liberals and its protected speech.
It is just a really stupid thing to do, and doing it to total strangers for no reason but the type of vehicle they are driving is absurd and nasty.
When trump was campaigning, his supporters basically said that they were upset because people were ignoring them and their issues and Clinton said that there were "deplorables" among them. Then he wins, and instead of simply working to get their issues addressed in Washington, they come right out and prove to the nation that they fit the stereotype of a stupid redneck. I thought that they wanted to be respected.
Actually, the Liberals have refused to work with the Deplorables or President Trump since the Trumpster took over. All they have been doing is phony witchhunts, refusing to do anything as far as immigration, healthcare, the Wall, even the confirmation of justices.
The Deplorables would have loved to work with Liberals for the good of our country, but they've only received the finger from the leftards.
Working with someone is much different than capitulating to them, which I think is what you're demanding. Investigations into suspected wrongdoing are not "witchhunts." Something should be done about immigration and health care, but maybe not to your satisfaction. The wall thing is just a jackass money-wasting proposal. May I remind you that Obama's pick for the Supreme Court was never even given a hearing, republicans never have advanced any viable healthcare proposal in the decades they had to do so, republicans even failed to attend meetings to reconcile competing bills passed individually by the House and the Senate. They completely refused to cooperate with President Obama.
The "deplorables" neglected to send intelligent, organized, and well-spoken people to Washington to explain the policies they espouse and answer the questions raised. Now we have a mentally-ill person in the Oval Office who does not have even a basic understanding of the U.S. Constitution, who has completely muddled foreign policy and put our country in danger and can't understand the professionals who work in our intelligence and diplomatic communities, and can't get competent people to work for him, and a sex queerdo who makes funny faces in the Veep's chair. Complete incompetence.
Incidentally, your repeated references to Jewish people as "Kosher people" is a prime example of the idiocy of coming from the "deplorables." It's just dumb.
