In the UK, Why are the people so brainwashed by Political correctness' Multicultural ideology?

They do not care about their own people/future children are being targeted by the ' Divide & Conquer ' technique by Zionist organisations who pledged plans for this in the early 1900's and again in the 40's. it works by forcing white cultures to intermix with third world people, which would lead to the destruction of identity and racial tensions, which could pave the way for their own agenda of ending European countries sovereignty and creating the EU super-state. This of course which will eradicate all boarder patrols too.
