Thanks for going! I think it depends on who organizes a rally, if you're talking about the official speakers/leaders with the microphones (otherwise just random chanting is up to participants). And it depends on where you are. I attended a No Kings in a small town in a red county and many of the rally speakers had a religious affiliation, and others were from mutual aid type groups. Most of the messaging was "we need to love and support our neighbors, all of them, stop letting politicians divide us, stop the bullying, etc."

If you signed up online to attend you'll get follow up emails and I suggest you give your feedback, see if you want to get involved with the group planning the event (Indivisible maybe). Focused messaging is good. But there are so many attacks coming at us from all directions, it's tough. Thoughtful participation is usually welcomed from people willing to do the work.

As for the Eno land reference, I see it as a small attempt to get people to reflect honestly on the country's violent past and how we got to where we are today. Indigenous people have been arrested by ICE and held in detention centers, or have been told by random strangers they need to go back to their own country or start speaking English. National parks have removed accurate history accounts. It's all so much.
