Like the Trump supporters, the supporters of the 'exit' campaign were older, less educated, and more xenophobic... and now many are openly expressing shock at the damage they have wrought - in a day the UK went from being the 5th largest economy to the 6th, there is a great likelihood the UK will splinter with at least Scotland opting to leave...

So what you are saying with your post is "Look! See, a bunch of angry, ignorant bigots made a horribly self-destructive choice on the other side of the Atlantic, why are you so upset I want the same for the US?!"

Trump promises you ridiculous things, with no possibility of delivering them... he flat out lies many times a day and changes his positions 180 degrees in the course of a few hours. The people supporting him only swallow it because he covers it all with a generous helping of Bravado, Bluster, and open bigotry... he promises to stick it to the brown people, that thrills you... because you have let him convince you THEY are the reasons for all your failures.

The choice the UK made to exit IS being celebrated by the fascists there and across Europe...

A jubilant Le Pen delivered a Brexit victory speech from her party’s headquarters outside Paris, styling the UK referendum result as just the start of an unstoppable new wave of support for parties and movements like the Front National. “The UK has begun a movement that can’t be stopped,” she said.

Le Pen swiftly changed her social media handles to the Union flag and stated her “warmest and friendliest” congratulations to “very brave” Boris Johnson and the leave campaign. Specially printed Front National Brexit posters showed hands breaking free from chains, with the caption “Now it’s France’s turn”.

In the Netherlands, the far right and anti-immigration leader Geert Wilders called for a referendum on Dutch membership of the EU. “I think it’s historic,” he told Dutch radio. “I think it could also have huge consequences for the Netherlands and the rest of Europe. Now it’s our turn. I think the Dutch people must now be given the chance to have their say in a referendum.”

The far right Sweden Democrats, meanwhile, who hold the balance of power in Stockholm, tweeted: “Congratulations to Britain’s people on choosing independence! Now we are waiting for a #swexit!”

In Athens, Golden Dawn, Europe’s most violent rightwing party, rejoiced at the referendum result. Predicting it would further empower “nationalist forces” across Europe, the neo-fascist group welcomed what it described as “the brave decision of the British people” and said it hoped a similar referendum could take place in Greece.

“Golden Dawn welcomes the victory of the nationalist and patriotic forces in Great Britain against the European Union, which has been transformed into the doleful instrument of loan sharks,” said the party’s leader Nikolaos Michaloliakos.

Debt-stricken Greece, the eurozone’s weakest link and until now most volatile member state, has been bailed out three times since 2010. “I hope that sometime a referendum can be held in Greece, which has been brought to its knees economically and enslaved, assigning its national sovereignty to the Europe of usurers,” the leader, an ardent admirer of Adolf Hitler, added.
