Another difference seen only after the protests.
Their side: Tons of trash left behind. Thousands of dollars and plenty of man hours to clean up.
The good guys: Little to no trash left behind and in many cases less trash is there than before the event. Many of the good guys bring garbage bags.
Yes...I remember standing with the DC Chapter of FR and a bunch of US Marines in civilian clothes at the big grass circle on the other side of the Potomac River from the Lincoln Memorial where the Arlington Memorial Bridge is, and the unbelievable mess the Leftists dumped on the ground was astonishing. Soiled baby diapers, half eaten box lunches given to them, signs, flyers, candy and food wrappers, you name it.
It was nauseating.
When we left our area in the large grass circle, we policed the area, and left it as clean as we had arrived. (IIRC, there were at most about 40-60 of us conservatives there, and we weren’t inclined to crap in the bed we were sleeping in anyway, so there wasn’t a lot.
It was notable, because one of the Marines with us ended up on the front page of one of the Washington Post editions (I think) when he was being held back by his buddies.
IIRC, while visiting my dad’s grave, I ran into those guys the day after at Arlington visiting the grave of one of their buddies KIA in Iraq.
Good guys. I kept in touch with one of them and his mother for several years (She was driving the group of them around, IIRC) but lost touch.
