This is one of these areas where xenophobes have a huge amount to answer for.
Migration absolutely should be discussed, like every economic issue and every other part of local services planning, etc etc.
But all my life, it has been extremely hard to have any rational discussion of it because as soon as you start, xenophobes come out of the woodwork complaining about the "Them". "Their" food, or music, or "them" marrying "our" daughters
... It's endless.
You then get a knee jerk of people trying to pre-empt the xenophobic attacks.
And it all goes round in a horrible dance.
The end result is we become unable to have any kind of constructive discussion, of the kind we might expect on, eg where to build a new hospital.
