No it's not. You vote for MEPs. And Brussels has limited authority as agreed upon by your sovereign bodies. Hell its limited authority is its largest problem since it lacks the power to fix accounting imbalances inherent in a currency union*...which the UK isn't even a part of!
You ponces literally voted to cut your nose to spite your face. The majority of your excess labor and exports are services (finance and education and so on) and you just voted to give all that up. And then on top of that you're not going to get better deals with anyone as you were because your prime advantage to non-EU states was as a stopover into the EU! And then, on top of that, entry into the single market will require abiding by EU regulations anyway so you literally just voted to have less representation! And then there is the fact that the rest of the Union actually wants to stay so you might have just screwed 300 years of tradition and Union so that you could be worse off.
The mandate for a European Union is literally world war 2 in that "you know this is he second time we have done this recently maybe we should take steps to ensure that our nations, being intertwined, do not do it again".
And people in the UK are probably less worried about annexing France as they are getting hit by a
Molotov cocktail. . So you know actual tangible holy *** fascism right here folks, in your England.
*basically the reason why the US doesn't run into Greek style crisis is because the Federal govt subsidizes States off the books. These imbalances occur because currency fluctuation should occur to deal with productivity differences but can't when currency is unified thus no equilibrium in either capital or good current accounts.
