I'm worried that we won't be a distinct people, culturally and ethnically. I gave the example of Sweden. It has nothing to do with superiority or any such thing. The current situarion, should it continue, is a death sentence to our people. Blood, sweat an tears.
There was a 30 year civil war in Sri Lanka, supposedly over precisely that - though it was hard to tell as the politicians, Buddhist monks, charismatic militants all got involved to whip up violent nationalism and it stopped being a debate and negotiation and turned very violent - quotas to maintain the ethnic majority's privilege rather than basing education and jobs on merit, suicide bombers committed to the cause etc
My mother was very non-violently committed to the idea of preserving cultural heritage but eventually she had to concede that it was impossible to control that or legislate for that - people were going to inter-marry, populations were going to fluctuate, people were going to adopt other cultures and religions as they were exposed to new ideas.
From my perspective as the member of a minority, I was slightly baffled by all the worry about offending minorities here in the UK - maybe those kind of ideas are where people should seek change rather than banning people, because my experience is the more you molly-coddle someone the more fragile they seem to get collectively. Maybe that's why previous generations of immigrants were more robust and prepared to integrate. I grew up here during the racism of the 70s - you just got on with it and tried to fit in, and people started giving you a chance once they got to know you.
My community takes the same view in terms of giving aid to Sri Lanka - certain communities in Sri Lanka seem to have developed a dependency culture that was never there before, so we stopped doing so much and told them 50% of the effort needed to come from them, despite the bombing, torture, deaths, living under the rule of militants, living under the rule of the army, rape, female sexual exploitation etc etc they had endured. As time passes and as the younger generation who didn't experience the war grow up, more and more people in those communities are starting to show enthusiasm for helping themselves, especially as their community are encouraging them because they want them to have a future.
