That’s hyperbole and inaccurate - left wing posters have discussed immigration issues. In particular, there have been discussions in relation to Brexit, and immigration patterns and numbers changed massively after we left EU. It would be really refreshing for those on the right - Johnson, Farage et al - who championed Brexit could have an honest debate about that.
Your point about housing is a complex one. Maybe I’ve interpreted you incorrectly, but while immigration will have an impact, particularly in urban areas, that’s only part of the issue. Successive governments have failed to build enough houses, particularly social housing which was further depleted by the ‘Right to Buy’ scheme. We have an aging population, many of whom still reside in family homes, which is all good, but again impacts on housing. There has also been a huge increase in people buying second homes - many in rural areas - which has caused huge issues for locals looking to get on the property ladder.
As someone who is left-wing, I think we do need a considered discussion on immigration, but it has to be part of a much wider context. The issue with Reform and the Tory’s election slogan of ‘Stop the Boats’ is that becomes a single, dominating issue - and leads to the populism of Farage, ‘This is the issue, I’ll fix it’ without any real substance, or seriously alarming policies like sending female Afghan asylum seekers back to the Taliban.
And while I know that there are many across the political spectrum who have genuine concerns about immigration, there are also a (hopefully) small but loud voices who are racist and bigoted. Seriously, you should see the bully boys who are backing up Reform councillors in my hometown, which means that local people are too frightened to post any criticisms about them on social media.
