how far?

One of the old boy regulars frequently starts conversations about immigrants. I do my best to politely disagree, pointing out that he has spent most of his working life exploiting the financial benefits of working abroad and recouping appropriate tax benefits under a system of world financial imbalance created by violent racist colonialism, and to denigrate others for attempting to begin to redress the balance from their point of non-violent, non-colonial disadvantage is a little hypocritical.
At what point would it be reasonable for me to inform him that his ignorant racism, selfishness and general offensiveness is akin to fascism and banish him to a thirld-world war-zone in order to investigate why he needs to take his head out of his arse?
