Middle class people's class position depends on them being reactionary and antagonistic towards their "inferiors."

There is nothing one can do to debate people like that, because to take you seriously, they'd need to realise their position in society as exploiters and beneficiaries of bourgeoisie exploitation as unjust.

Which is why they are the main faction for fascist recruitment, as then they won't have to feel bad about being parasites and can continue profiting from unjust labor relations.
