Before Brexit the chosen enemy was Polish people/generic eastern Europeans. They are ostensibly white, but many conflicts were over the number of them that were coming to the UK to work, despite that they were mostly doing jobs with high demand like cleaners.

It's only since Brexit that non-European immigration has skyrocketed, as well as the onset of the small-boats issue, since we can no longer send them back to France.

Don't re-write history.
