My grandparents would’ve already been on the White House lawn and Capitol steps with tar & feathers, pitchforks, hempen rope and other equipment.
It was the WW1 generation (our grand parents) that brought progressivism to the USA. Just take a look at the damage done to the USA by Wilson 1913-1921. So no our grand parents would not be on the White House lawn. Maybe the civil war generation would but definitely not the WW1 generation.
I have for years worried about the country once the Nam vets are to old to much of anything. That day is rapidly approaching.
