That’s like saying in 1940 “if the UK were to fight Nazi Germany by itself, it’d be consigning itself to historical irrelevance.”

Correct. Britain should retain their autonomy... Strength and individualism.

No, it's not the same, in fact your statement is the exact opposite of what the UK did

A brexit would be akin to the UK saying in 1940 "we will be neutral" -- a UK outside the EU has no ability to influence the EU and many EU member states (like POland, Hungary) have looked at the UK as a way to balance the Franco-German axis

If Brexit happens, then SCotland will break away and you will have just England (Welsh nationalists would also break away, albeit reluctantly) -- England would be a small country with no agricultural or manufacturing base and heavily reliant on financial services -- and those financial services will move away: to european bourses and to Dubai, Singapore, Hong Kong and New York

The UK would be consigned to further slip into irrelevance -- like Rome in the 12th century...
