As others say, you’d be mad - or part of the problem - not to be concerned. What we should be doing is looking at the reason why.
For example, social identity theory suggests that we naturally gravitate to/identify with the ‘in group’, it the group that has mor social cache, that is economically more successful, etc because evolution has taught us that that is the group, the tribe, that we need to be in to ensure survival and longevity for our offspring. When recourses become scarce or are threatened, membership of that group is important and often leads to targeting other groups - those seen as ‘out groups’ who are considered a threat. This is what happened in Germany after the great depression when Jewish people were seen to be affluent (in fact not just 1930’s Germany, but throughout history eg the Pogroms in York centuries ago). It is why people are feeling threatened by what appears to have been uncontrolled [legal] immigration in the UK [and other European nations] over the last 10+ years at a time when the post 2008 crash/covid/Ukraine war has had an impact on availability if resources and cost of living.
At the moment, fears over the resources (access to housing, benefits, jobs for young people under 25, the crumbling NHS, an education system that is too focused on identity based ideology and not ensuring every child leaves with an education and qualifications that reflect their potential etc) means that ‘identity’ has become core to that uncertainty - in this case national identity. In Germany, in France, in the UK, this is emerging as a fear of disconnecting with our cultural heritage and identity and feeding fear of, in particular, muslim immigrants. This is further exacerbated by the exponential rise of muslim, economic, illegal migration across Europe than NONE of the EU nations seem able to stem or to work together over. This has fed people from those communities, because they now also feel threatened and insecure, to close ranks and identify more with their faith and ethnicity than with being British. An increasingly negative destructive cycle of othering and alienation across many communities is the result.
Feeling othered, othering all people of different faiths or races, is an expected historically observed response, and one that all governments should have anticipated and acted proactively to counter.
I do fear the backlash, especially for my YA DC having to navigate it. But we need to stop shying away from difficult conversations if we want to resolve it. But very very few political parties want to engage because, ultimately, their existence is predicated on electability - in Labour’s case, the desire to be re-electable in 2-3 years time - so they shy away, leaving parties such at Reform and the Greens shouting loudly and bring that conversation into social discourse. What has happened in Germany (just as when R-wing parties surged in Italy a decade or so ago, and similar movements and parties were visibly growing in strength in France) should be a warning to the UK. It will take a brave party/a brave government to make the necessary changes - but it will need a brave and circumspect electorate to vote for them.
My optimism that we can achieve that in the UK waivers from day to day.
