I think you are ‘borrowing’ trouble. Picking a fight over an issue that doesn’t directly affect you.
And (as a child raise in a Muslim refugee family who arrived here in the 1970s) I agree with him that there is more nuance to this, that it has been simmering beneath the surface for years (hence the Brexit result) and it is far more complex than ‘racism’.
the most under privileged demographic in the UK currently is poor, white, working class men/boys - they are the most likely to be free school meals, have the lowest attendance record, the poorest GCSE/BTEC/Alevel outcomes, are least likely to go to university, the most likely to be on benefits. This is obviously bugger all to do with the number of Muslim/black/Asian individuals who have moved to the UK in recent decades, but a symptom of decades of neglect by successive governments and an increasingly inadequate state education system, especially in areas of high poverty.
What is abhorrent is that, egged on/manipulated by a small contingent of far-right yobs, people are targeting their frustration and anger at Muslims. MSM and SM are responsible for feeding people the idea that the issues they face - lack of jobs, poor educations, inadequate housing - is the fault of an immigration ‘explosion’ (!!) when in fact it is a systemic and deep-seated social problem that has been allowed to percolate for decades - probably since Thatcher broke the unions and we saw the decline of mining & the manufacturing industries that supported these men. We’ve all sat back and shrugged because we were all right Jack, but until we face up to the wholesale failure to address this issue, they will continue to be angry, feel unseen, unheard, and target those that seem to be getting on alright. The economic downturn post 2008, Brexit, lockdowns, the CoL crisis has just exacerbated these simmering feelings… but no one of any political party has stepped up.
Just like poor, white displaced and angry young men readily took up arms and focused their disillusion and anger at the Jewish community in 1930s Germany after the the depression caused by the 1929 Wall Street Crash…
So, I’d say your husband is probably not wrong and you, like many people, are being disingenuous to dismiss this as mere racism.
