You're talking about two very different sentiments. People see leaving the EU as a foolish decision. But Britain has every right to make that decision if it wants. I don't know of anyone outside of Britain who "hates" that they left (in the sense of feeling anger or offense).

In fact a lot of the sentiment tends to be more like "good riddance".

Interestingly there seems to be even more foreigners working in London now than before Brexit. Just with less rights I guess.

You're talking as though there were blue EU tanks rolling through the English countryside and bombers from Brussels flattening biscuit factories. Britain is not and was not oppressed, it's just a former imperial power with a heavily financialized economy that is no longer the biggest wheel in a larger regional economy.

Yeah the EU is totally to the UK like Israël is to the Palestians or Turkey to the Kurds. The EU put a wall around the UK and is slowly colonizing the area.
