If you voted for Britain to leave the EU because of the EU's "capability to be authoritarian", then perhaps you should have already voted (with your feet) to leave Britain because of its much worse capability to be authoritarian.
For example, it was Britain that introduced the Snoopers' Charter:

without any encouragement from the EU, and indeed that Act has since been found incompatible with European law.
Out of interest, can you name another example where the EU was authoritarian (acting in a way that the British government wouldn't have)?
