This is why being educated and understanding of what the Brexit means, what the EU is and what happens in the event of an exit without resorting to scaremongering about Britain being doomed, are essential to having this important debate about our membership.
Any 'Outer' reading this needs to understand that free movement of peoples, goods and services will not be affected by our exit and that as a member of the EEA (what we voted for back in the 70's) will still be in effect. Yes, we'd be allowed to control our borders, we'd be allowed to refuse the EU's declarations on accepting migrants and refugees, choosing our own accepted numbers or refusing entry entirely, but EU citizens would still be allowed to live and work in the UK as well as vice versa. That wouldn't change. There are some outers who want us to leave Europe completely (not my view) and there are those, like me, who want us to return to the original agreement offered in 1975, which IS what we'd be doing in the event of a 'Brexit'. Agriculture and fishing laws imposed by the EU would no longer have any effect on Britain. Policy making in Brussels would be null and void. TTIP, if imposed, would not be recognised by Britain. We'd join the US, China, Russia, Norway, Turkey, Japan, South Korea, Saudi Arabia, Switzerland, Iceland, India, Brazil, Canada, the UAE, Hong Kong, Algeria, South Africa and Nigeria as nations that trade with the EU, but are not governed by them, which is what we want.
A referendum on Britain being a member of the EEA is a debate for another time; this one is about leaving the totalitarian political 'union' with Europe, that sprang up and claimed dominance over the rest of us without anyone having a say on the matter.
