You don't have to think both sides are morally or rationally the same to have empathy for both sides. The alternative is either mass slaughter or mass displacement, at the extremes. You can't eliminate your "enemy" without either murdering/displacing them or somehow coming to terms with them (ideally, being friends with them). MLK got this right, and he was able to say this without compromising in one iota his stances on social justice, class justice, etc.
