Brexit has caused severe damage to this country
Not everyone agrees though.
And even if you calmly produce statistics that Brexiteers accept showing this damage, they then move the goalposts and say "Yes, but it was worth it".
And so the cycle believes.
Remember, there are genuinely some folk who despair over the repeal of the corn laws. They are a tiny tiny majority of those that originally opposed it.
In 100 years time you will still find someone who supports/supported Brexit.
And frankly the corn laws are positively contemporary when you consider there are some folk who bemoan the abdication of James II.
