I guess any question about the UK and a second referendum now doesn't matter.
Given the EU appears to have just voted to commit suicide by alienating the youth and internet savvy folks who form the base that actually stops more countries leaving I think we can reasonably bet that
Any UK second referendum will feature an anti-EU campaign about article 13 and how corrupt the EU is - aimed at the people who matter (the younger vote)
It it turns into the mess that seems likely then the anti-EU folks in other countries are going to follow the same path.
Not only that of course but due to article 11 the anti-EU trolls can post any garbage they like but nobody will be able to post real news links in response without a licence. Turkeys really do vote for Christmas sometimes.
