I never tried to deny or downplay the atrocities perpetrated against Native Americans. Honestly, I find it difficult to call it anything less than genocide.
But back on topic:
The picture on the right is of a responsible officer assisting an old man, who is a part of the KKK, in recovering from heat stroke. That has so much more honor and dignity to it than the one on the left. Don't get me wrong, the KKK is fucking stupid and abominable. But don't call such an amazing deed by an officer "bullshit" when it does far more to challenge racism than violence ever did. And I'd say a Klansman owing his life to a black man would be a fate worse than death for him.
The picture on the left, however, only kindles the fire of hatred among racists. You're literally supporting giving the bad guys ammo here. Does that person deserve it? Assuming they're in the KKK like the one on the right, absolutely. However, if you choose to fight with kindness instead, they cannot touch you, and the media will be much more inclined to talk highly of you.
