Anger at injustice is universal. Everyone feels it the same way, the one sitting at home and the one standing in the square. It needs no education, no courage, it comes uninvited the moment someone watches a person slip out of the guilt they should carry. In this, people are equal.
The ability to stand up to it is not equal at all.
One person swallows that anger and goes to sleep. Another carries it for years like a stone in his pocket, never sets it down, just gets used to the weight. And then there is the rare third one, who one day stops counting the losses. This is where equality truly breaks down, because acting means risking everything you have, while staying angry costs nothing.
And when that anger finally turns into action, it stops being universal at all. Violence almost never aims at the system itself. It aims at a specific face, a specific name, a grievance a person remembers down to the last detail. Violence tends to be a personal matter, even when it wears the mask of justice for everyone.
That is why those in power are not afraid of a crowd that only shouts. They are afraid of the one who stopped.
