Re: Do you want a second referendum?
Your first paragraph I agree with, but I would like to fix your second para:
Problems for Leave in the last Euro elections is the support for Brexit party was split towards the main incumbent party (Conservatives) who have centuries of historically loyal voters, while the Leave vote was scooped up almost totally by one party in each region (LibDem or SNP), which inflates their perceived support. We can’t interpret votes for Labour either way on this issue. Also, at least some LibDem voted due to their support for other LibDem policies, whilst being Leave voters. Otherwise you are saying that nobody voted LibDem policy alone.
To be clear, this is facetious, but your argument is equal and delusional.
