I defend people who share the same values I have against those who do not, regardless of how powerful or powerless they are. What does relative power have to do with being worthy of being defended? Nothing! When the Palestinians decide to implement peaceful protest, become capital L Liberals and stop murdering people, maybe I’ll feel different about them, but until then, no sympathy what so ever.
My compassion for someone isn’t singly dependent on how much power they do or do not have! It depends on what they do with what power they do have.
I would be suspicious of anyone defending someone for the sole reason that that person or persons are less powerful. Decency matters!
