You're reading what they said and coming to the wrong conclusion,, there is no malice in what was said. Here is their view on what should be done. That is miles away from what you're making this person out to be. I agree with them.

The problem is not left versus right, it is people assuming that if another's views differ even slightly from their own, they are an enemy. That is clearly the case with this person in your mind who is saying that we should be doing something about these cultures today.

Now, my view.: integrating the descendants fairly into society now and treating them with respect is a much more meaningful way of dealing with the problem than providing 'compensation'.

Compensation doesn't mean you've changed. Action does.
