Were left wing, BLM groups actively discouraged from going because leading voices knew it would be best not to or was there just some collective sense it would be best to stay away? Just curious as I don't know much about how they are organised
Everyone knew what was coming.
The events of Charlottesville a few years ago were the hint that the MAGA groups are not at all engaged with the formal political process.
My guess is that there has been contact with the Democratic Party with advice given to stay the heck away.
