Seems like you just validated my point - a place without open borders is where a major outbreak of xenophobic violence is occurring, as opposed to mainland Europe.

It's not, I live in Switzerland, which has one of the highest rates of migration in the EU
> there was a palpable uptick in xenophobia when Romania and Bulgaria were admitted into the EU
I'd be curious to know what this looked like at the time. Regardless, even if we accept it as an example, that doesn't set the rule or show a general causation between open borders and xenophobia

Omegalol - you might want to look up what modern day xenophobia in SA looks like (as well as the current socioeconomic situation) so you can see why that probably wasn't a concern pre-20th century
