I think it trolling. That and a lot of 'not tight' marching tells me that this was a widespread protest by a lot of participants to being used as props in Trump's narcissistic fantasy wetdream. I think I love that they are thinking feeling humans who found a way to show it but avoid trouble.

I was just thinking, that ain't marching; that's strolling. Good choice.

I believe they know Trump doesn't know the difference.
