Centrists, we need to talk. I need to you understand some things. And I need you to do engage in some honest self-examination. If you're capable of that.
Have you ever noticed that the position of "both sides are bad" and "violence is always wrong" and "everyone should be allowed to speak/march" are A) extremely simplistic to the point that they require little to no actual thought and B) don't require you to do anything?
Centrists/moderates/whatever tend to act like their position is so enlightened and rare and above everything and better than everyone. Fact is, their position is very common because it's extremely easy. All it requires you to do is spout off a couple useless platitudes that are too simplistic to apply to a complex world and then you get to feel morally superior while coasting on the fact that at least you're not in the side of eugenics and genocide.
You don't have to march. You don't have to organize. You don't have to fight. And so you have to ask yourself - are you only clinging to the middle because it's easy?
And if you're not willing to entertain that question, I'm going to press you further:
"If you are neutral in situations of injustice, you have chosen the side of the oppressor. If an elephant has its foot on the tail of a mouse and you say that you are neutral, the mouse will not appreciate your neutrality." Desmond Tutu.
Your centrist position serves the oppressor. Your centrist position supports fascist and white supremacists and Donald Trump. You think you haven't chosen a side, but you have.
And the rest of us know it.
