For me there is a simple argument which can be easily understood by everyone. Larger groups of countries in this global economy are stronger than individual countries. Or alternatively to quote Aristotle "The whole is greater than the sum of its parts."
This is simply common sense and those in favour of brexit are simply deluding themselves that Britain will somehow be better off standing on the outside looking in. These are probably the same people that believe we still have a British Empire.
I would agree that Europe is not perfect but let us change it from within not leave in a hissy fit. We are stronger working together and we must work together for a better outcome for all. We must look outward beyond our island than inward and hope for the English channel to protect us.
Some 'pause for thought' comments from the first few days of campaigning:
"But in my view - for reasons of security, protection against crime and terrorism, trade with Europe, and access to markets around the world - it is in the national interest to remain a member of the European Union. " - Theresa May.
Although the brexit campaigners are arguing exactly the same about leaving. Again if you use a modicum of common sense team work would triumph over going it alone. After all terrorist groups are generally global operating in a number of countries so surely it makes sense to work together.

"I once asked Rupert Murdoch why he was so opposed to the European Union. “That’s easy,” he replied. “When I go into Downing Street they do what I say; when I go to Brussels they take no notice.”"
If that doesn't convince you to vote to stay in the EU then nothing will...
