French Presidential Election

[Viking]

But isn't the problem, Viking, that the groups in question are already isolated? This is distinct from isolating groups for the application or construction of policy (though in fact the former carries on from the latter a fair extent in recent history).

Not sure what you are saying here (which groups isolated how?).

There is an incredibly large gap between infected individuals and potentially dangerous demographics.
That argument is completely useless. You could lock all poor people up with that argument.

You could, but most would consider that unethical and overkill. It's different from telling people that they should rather stay in their home country or migrate to countries that are more culturally similar.

We had 3300 traffic deaths and maybe 20 due to islamic terrorism in 2016. Now I don't have any statistics on who caused all the traffic deaths and why, but surely old people would account for 20 or more of them?

Presumably, but there are at least a couple of things to consider:

• how many of the dead were elderly people (and should therefore be subtracted from the total), and how many non-elderly people were killed by elderly people as an overrepresentation (relative to the rest of the driving population; the actual number we are looking for)?
• how easy is it reduce the number of deaths and injuries resulting from traffic relative to those resulting from terrorist attacks? Presumably, the government is already spending a great deal on road safety, the police and counter-terrorism.

I get that you can't just put 340000 immigrants into a city of 340000 people and expect it to work out just fine, that is actually besides the point now. Just as it is useless to take one city as anecdotal evidence and then make some vague claim about how problematic mass immigration is.

It's not an anecdote, similar things are happening/have happened in many cities in Western Europe and form part of a larger statistic. For example, the Köln assaults last year match the general pattern of antisocial behaviour. Malmö is just one place where this phenomenon has turned particularly extreme, and could represent the future of other vulnerable cities if immigration pressure and government policies persist.
