You need to learn the difference between Europe the continent and the EU the political union. The two are not interchangeable.
The British continued to be European post 2020
Also, being geographically close, and only recently an ex-EU member, and with strong alignment on defence/Ukraine, it is not like we are wholly separate and unaligned. We retained some EU law, such as GDPR and EU261 (copy-pasted into a law referred to as 'UK261'). Yes, I understand the UK not being a member state means that EU laws wouldn't automatically apply – but the world is more complex than that.
The Labour party shares a lot in common with many parts of the EU and EU governments when it comes to control, privacy etc.
The UK has been re-aligning with the EU and the rest of Europe for a little while now, repairing relationships, for obvious reasons.
Learn the difference and use them correctly and respectfully.
