They may be useful for social cohesion within a group of people

Or not

true, however groups tend to drive towards social structures that promote laws that promote group cohesion, and specifically allow purging of members in one way or another, to maintain cohesion

usually banishment

If a right serves a purpose we want then it is a useful tool. If it does not then it's a hindrance. That's what everyone thinks deep down

And yes they can be changed obviously they're changing all the time

I think we should bring back exile

Sure

Become a vagrant, and a vagabond.

Frowned upon everywhere you go.

I guess that person could just claim refugee status though.

Well if we're accepting refugees from around the world it will be hard to exile any

They'll just come back as refugees

Well, you can't go to a country you have be exiled from...

That's the point of exile.

Plus these vagrants may end up becoming bandits

They'll go to the next white country

By way of death.

An exile from the US will go to Canada and an exile from Canada will go to Europe

And of that country accepts them Despite our objections.

Then you don't allow refugees from that country.

And exile need not last forever.

It's just within that frame can that person honour the law.

All I'm saying is first we have to change the way we operate as a society and our obsession with letting everyone in/tolerance

Tolerance should not be confused with willful ignorance.

We should end the culture of willful ignorance.

We should end both

Tolerance is no issue.

As it isn't allowing anything, it's allowing things within a tolerable measure.

E.g. a foreigner who respects the laws and traditions of a country.

You and I differ

Why should we be interested in any foreigners at all?

Well, say your population starts dying of a disease.

Where will your labour pool come from?

Or your population starts being replaced by foerigners...oh wait

How will you improve the conditions in the interim?

Or will you just tell everyone to suffer it out and wait?

Like here in Canada we are running out of medicine.

Well, even if we replace the dying native population with a new one the dying population still dies

And our labour force is basically dead.

So the dying population isn't improved any
