Protests should be peaceful. However, if we make a rare exception (without hurting anyone or harming their property), then it could be the toppling of the statue of a slave trader. The figure of the slave trader E. Colston stood in Bristol until last weekend. It's estimated Colston sold about 80.000 slaves, 20.000 died on their journey and were thrown overboard. In those days, sharks learned to seek out slave ships.
