It's a good sentiment, but... it's really not as simple as you're making it seem.

[Sango is a little weary of this. She's had her share of mistreatment from Exiles, even though she literally went blind trying to help them during the UE bombing.]

I'm not going to stop helping them when they're in need, but there's too many of them that are too hateful, too many Transports that will take the opposite direction. Unless you can convince every Transport to be helpful and kind, they're still going to have and use their scapegoat.
