Anyone who doesn't accept the outcome of free and fair elections with the will of the majority being enacted (see all previous UK General elections/referendums) is an extremist loon.
Anyone who accepts the country going down the crapper for a false ideal poorly executed by a white minority government hell bent on staying in power and servicing themselves and their chums with as much filthy lucre they can possibly get before bowing out and leaving the British people to suffer the mess, is, in my 'umble, a ****ing loon.
