Will they then go back into the EU and once again be subject to the Muslim invasion?
They've had more Muslims, and worse Muslims, than any EU country, they got them on their own.
The UK Muslim problem is their own doing, and has nothing to do with whether or not they are in the EU.
They never left the EU. That’s what this is about. This is about them negotiating leaving the EU and this is a vote on the terms and conditions of them leaving. Not certain why you are confused about that.
They’ll have elections, and Theresa would do well to step aside and allow someone else to carry the Tory standard. Chamberlain did that in 1940. Is she more small-minded than Chamberlain?
