I don’t understand your reasoning. Imagine that you and some group of people crashed on a desert island. No help is coming, so you start building shelters, dividing tasks, and so on. Now one of the survivors is a total slacker who only take advantage of others work, do nothing to help and is aggressive towards other people. Now, do you think that the group have the right to expel that person from their little community? I think definitely yes! They “own” the place where they started their community, so they can force somebody to leave it (which doesn’t matter anyway, because a big smoke will come in the end and kill them all).
OK, I slightly exaggerated, but I still hold my opinion that in some cases the best way to achieve peaceful coexistence is by restricting the law. For instance, if we hadn’t law at all, our coexistence definitely wouldn’t be peaceful.
This is a faulty assumption. You should consider who emigrate in the first place - in majority, these are people who don’t have any perspective for better life in their own country, very likely low-educated, people that very often come from poor family (and I mean massive emigration, like the one which took place after UK opened their borders in 2004). And guess who is more likely to commit crime, people with no perspectives in life or people that have a good job and some purpose in their life?
You know, two centuries ago possibilities for a transport across a continent where considerably limited. How would they migrate, by foot???
That’s a bullshit, considering that Rome started building their empire when they had the Senate with the support of Roman citizens. And the divisions are something natural - people have the need to identify with some group. When there is a lot of immigrants which doesn’t integrate with locals you have two groups on the same “territory”. This only asks for trouble.
Of course not, so that’s why it’s important to debate on this topic. And believe me, there is a lot of people who think the same way as I do.
