I truly wish that America could band together like this. We have marches, but it is so difficult in our current presidential situation to get the legal backing for it, that they are few and far between, and when they do happen, are very often "moderated" by riot control, even though they are legal and peaceful protests. The "other side" also chooses to make them appear as though they are riots that go out of control.
