Protester

Extracted from the Wikipedia article Protest.
A protest itself may at times be the subject of a counter-protest. In such cases, counter-protesters demonstrate their support for the person, policy, action, etc. that is the subject of the original protest. Protesters and counter-protesters can sometimes violently clash. One study found that nonviolent activism during the civil rights movement in the United States tended to produce favorable media coverage and changes in public opinion focusing on the issues organizers were raising, but violent protests tended to generate unfavorable media coverage that generated public desire to restore law and order.
