Do you think the photo you're seeing is the entirity of this protest? I think you don't actually grasp the size of the US.

This is a small turnout, relatively speaking (this one was "cancelled" so I imagine it would have even had more). I went to one in a pretty centrist-right leaning town (Much much smaller than Minneapolis... Like hundreds of times smaller), and our turnout was about the same as this photo.

Go look at the turnout for Philadelphia.

I haven't seen any nationwide estimates yet, but I can pretty much guarantee that it was at least more than 1 million people. at least

Assuming you actually give a shit and aren't just here to sow division.

Edit: I'm now seeing figures of around 4-6 million people total, with some places estimating as many as 12 million.
