what constitutes a foolish dispute? Now that's a loaded question... Lol
You just described the POTUS.There is an argumentative spirit and a mocking spirit. They often come together and have certain characteristics. You cannot win an argument with someone with an argumentative spirit because you're arguing with a demon. It's impossible. They don't agree to disagree, they don't give up, they just keep you distracted. That's their job. You'll often find that these people will purposely pick arguments and post things on FB in order to rile people up, and start YELLING for no reason. They also get 'triggered' easily.
I have a family member like that, and I just avoid arguments around this person. I will just nod and smile, or I will say that I respectfully disagree but they are welcome to think what they like.
How's the weather?Oh Mojo, don't get me started on the POTUS...
