I think people's defensiveness can get in the way of empathy.

I would be somewhat dismayed if someone asked me to denounce white supremacy, because I would hope that it would be obvious that I abhor white supremacy.

I don't think I'd be insulted, though--and certainly not to the level of refusing to do any denouncing. Of course it's wrong! Hope to live in a world where it goes without saying. Until then, happy to repeat as often as anyone cares to hear it.
