Yes I can guess where your prejudice comes from
Why prejudice?
the definition of which is this:
preconceived opinion that is not based on reason or actual experience.
I can't speak for Gordon but for myself I have plenty of actual experiences where my opinion is based on fact.
As a completely arbitrary example the fact that the government allows infrastructure expenditure to be 6 times more per head of the population in the capital than in other areas. Grossly unfair, actual experience.
Another example, the Windrush generation.
These are actual reasons and experience.
So not prejudice.
