This is your idea of "dangerous"??

The UK is a sovereign nation. They can do what they like. The EU should break up, or at least stick to doing what works - handling trade - and stop trying to be a one-world government.

What's with all this talk of punitive and spite-based politics? You believe the EU needs to ensure economic hassle befalls the UK for having the audacity not to want to remain in the union? That's absolutely beyond the pale. The UK is the 2nd biggest economy in the EU. It would be mind-numbingly stupid for either the EU or the UK to want to inflict economic harm on each other out of some foolish notion of spite over being jilted.

That's really no different than the right wing kooks who wanted the US automotive manufacturing industry to collapse in 2008, because they would rather die and take others with them than see someone they hated get a bailout.
