I don't know why you are staggered RayneDance. I am pretty sure that going into the then EEC was part of the Tory manifesto at the time. Heath, rather to everyone's surprise, won in 1970, and allowed his Parliamentary representatives to get on with the job they were elected for. Even the Mail was an enthusiastic supporter of the EEC. Since then we have had numerous elections - let's see, two in 1974, one in 79, 83, 87, 92, 97, 2001, 05, 10, 15, 17 (this last completely unnecessary, but no matter). Hardly a suspension of democracy. By contrast, Referenda haven't been the normal way we conduct Government business and the 2016 one, was held because Cameron was trying to silence his extreme right wing, and ran for the hills as soon as he failed. Since he almost certainly didn't expect to win the 2015 election, he expected to use Lib Dem blocking as an excuse. A weak man, who I hope will go down in history as one of our worst PMs.
Immediately after the War the USA started promoting the Cold War, which may have helped 'sign Eastern Europe over to Communism'. It may have happened anyway, but it predated the EEC/EU by about 10 years, so I don't think W Europe and the original six can take any blame for that.
How can people 'sign away rights after world wars and dictatorships'? Because the people signing up for the original EEC, the original six, had had an absolute bellyful of dictatorships, with millions killed, many more displaced and towns and cities ruined and knew that they had to find a better way.
As for your wittering on about them- thank your lucky stars that you haven't experienced a Dictatorship; you might change your tune if you did. (Instead of the usual Leaver anti-German claptrap)
