Is Rolling Coal a pro-Trump thing, or is it just an anti-anthropogenic global warming thing?

It is purely obnoxious and noxious. Most pro-Trump people I have met respect others. Anybody that does things like that is just asking for trouble and I would cheer if I saw them getting a ticket. I had to Google it to even know what you were talking about.

Neither it is a stupid I want attention thing.

When my brother was about 11 and I was 8, he would come into the room, sit next to me to watch TV, and let off the biggest fart he could muster just to get a reaction out of me.

Point is, rolling coal isn't a pro-Trump, anti-liberal, or anti-global warming thing. It's just an infantile thing.

It's an anti-human being thing, because it's bad for the health of people near them. It is something that very, very stupid people do. If you see someone doing that, take down their license plate number and report them.
