Crow Sister: I assume "council estate" is perhaps what here would be called 'the other side of the tracks' (which is where I grew up)--with grandparents and a mom who cared.
I agree that the obvious answer is that the poster is poorly educated, or very drunk, or both. But that doesn't excuse racist claptrap. Being 'stupid' because of early conditions in one's life I can understand. Staying stupid is another animal completely. Being both stupid and hate-filled is, imo, a personal choice the fellow made. I expect he had guidance from his Nazi friends.
