We want our sovereignty, control over our country, out lives.
We joined the EEC, a trading agreement and standards organisation that is now trying to become a Superstate, like the USA, nobody wants this, but some on the left see it as a short term way to get their wishes politically.
The EU is Skynet, a self aware beast which is threatening us if well leave...? Why? Because the Eurocrats great gravy train will derail.
They can rot in hell, we will never accept the EU whatever the vote is.
