I observed one such protest today. These people are now past the denial stage and into anger.
There were no giant puppets and the signs were all handmade. Obviously it did not occur to them to prepare for Trump’s victory.
Sample signs: “Trump Does Not Represent Me!” (no duh.) “Pu$$y grabs back!” (ewwww!)
There were also chants. “Trans lives matter!!!” I haven’t heard that one before. They also made noises about abolishing the electoral college.
