Brexitears are beyond reason now, and have been for a long time.
They only care about their 'prize' which is simply to be able to say "we win, you lose", regardless if this is good or bad for Britain.
Evidence, experts, facts, reason, information, all these things have become white-noise to the Brexitears.
They're just not interested in discussion or debate and, for them, democracy ended on the day the referendum result was announced.
Brexitears have made themselves irrelevant to this process.
The only group worth appealing to now is the government.
