In the US: call on government officials at all levels to remove all symbols that honor the rebel side of the civil war.

The purpose of their rebellion was to perpetuate slavery. The Union soldiers fought to end slavery, and sung about that as they marched.

No matter what admirable personal characteristics some southern leaders may have had, that can't redeem the evil that they fought for — not even slightly.

Protesters in North Carolina (not so far from Charlottesville) pulled down a memorial to soldiers that fought for slavery.

Defacing a statue reduces the dignity of those who do it. Pulling the statue down is more dignified. However, the best form of victory is to pressure officials to remove the statue. For a state to have a special law privileging statues that honor the war to continue slavery is an endorsement of that side, which dishonors that state.
