Correct, remainers with outlandish claims about what might happen, which were made before the referendum, laid the ground for 'project fear' which the leavers scooped up with open arms...talk about giving someone a stick to beat you with , its ludicrous.
Leavers did not try to point to what might occur after Brexit except in generalities, e.g. 'taking control' etc.
Yes true, but the points were not made in general terms as you have above, they were specific things about, no fly zones, shortages of medicines, bans on travelling in Europe, etc. a direct attempt to frighten people, hence 'project fear', but it back fired because in many cases there were alternatives or at least tit-for-tat responses, which would hurt at least part of the EU as much as it might hurt the UK. At times it effectively became a 'pi**ing contest' with claim and counter claim getting evermore ludicrous.
