goon I've had a similar experience. I generally find it head scratching that migrants are seen as a uniform block that think and act a certain way. The guy moving to London on a £100k tech job does not view the world the same way as his countryman coming in on £30k as a blue collar worker or someone else coming into the UK for a PhD. Those groups don't have any overlap in their home country so why would that change just because they have the same stamp on their passport? There are absolutely migrants with problematic views just like there are those who are uber 'woke'. It's true that more often than not, this group will end up voting Labour but that's largely because anyone under the age of 50 would do the same and most migrants skew younger.
Raising concerns on immigration isn't a problematic position but, generally speaking, most that do end up making problematic arguments. I can understand why someone would think a net annual migration rate equivalent to the population of Liverpool is a bit too steep even if we had a competent government capable of building infrastructure. Equally I've wondered myself how sustainable it is to encourage parallel societies in one country is, I've met families where dependents are unable to speak English, largely not documented to the local authorities and are effectively slipping through the cracks for decades. The trouble is all this ends up being twisted by right wing populists who don't have a shred of empathy and view the world as a zero sum game. You then end up with Farage on the telly talking about how there are more potholes on the roads because of immigration or confront the awful reality that he once took the tube and no one spoke English.
There's nothing morally good or bad about migration. However, there are countries that do a better job at making it work for everyone than others and there are lessons to learn. Despite all the rhetoric, I've found countries like the UK and US have done a better job in recent decades compared to countries experiencing their first generation of migrants today. That's why I personally think Europe as a whole will be fairly anti-migrant by the end of the decade - more so than what's been seen in the 2010s across the US/UK. The only release valve would be having a party that's socially conservative and fiscally liberal - that's more or less what Johnson wanted the Tory party to be until Covid wrecked his plans. At an extreme scale, that's the model operated across the Middle East to make a migration rate of 80% acceptable.
