Most folk on HN would agree that discriminating on race is a no-no. But that is exactly what our constructs called nation-states do at their borders (Go ahead an try travelling as a Swiss national and then again as a Sudanese).
I think this is reprehensible and I suspect others will one day too. Right now - its not even discussed. Hence 'acceptable to the norms of the times'.
And here's the rub: not only am I considered a naive quack on this issue, but it would be quickly pointed out when a nation state with strict border visa requirements told of another state for doing the same.
You need to work through your assumptions more.

And? The point is that people are not their government. They disagree with what they govt is doing and speak out. What's your point exactly?
Again, your bad actions are not justified by the bad actions of others. I think you need to work through your logic, otherwise, you might end up justifying murder because.. well... people do it, right?
