Why doesn't he like being beaten?
It's bad for his fragile health.
Why would he conclude that those people who beat him up are friends of the <skin colour> people?

Because skincolour people were connected with and used help of those thugs ?
How do you know that any of these are even plausible trains of thought/outcomes?
