I live near Cambridge, which was one of the most heavily pro-Remain areas of the country. However, it was my experience during honest private discussions before the referendum that the vast majority of participants thought the EU had both pros and cons, and often fell quite centrally on the in/out scale. Extreme views were rare, and usually based on a single overriding principle, such as supporting Remain because of a belief that Europe would inevitably go to war within our lifetimes without the EU to keep it together, or supporting Leave because of a belief that the EU is fundamentally flawed economically and so our trade policy should be more global in ways that aren't possible as a member.
