They were British citizens.

Not all of them, and even for those that were, they themselves were oppressed by the British and were not the victimizers of Ugandans. It's amazing to me that you are undergoing these contortions to justify literal Nazi like behavior. This is what you are defending -

A system of work permits and trade licenses was introduced in 1969 to Indians' economic and professional activities. Indians were segregated and discriminated against in all walks of life. After Amin came to power, he exploited these divisions to spread propaganda against Indians. Indians were stereotyped as "only traders" and thereby "inbred" to their profession. Indians were attacked as "dukawallas" (an occupational term that degenerated into an anti-Indian slur during Amin's time). They were stereotyped as "greedy, conniving", without racial identity or loyalty but "always cheating, conspiring and plotting" to subvert Uganda. Amin used this to justify a campaign of "de-Indianisation", eventually resulting in the expulsion and ethnic cleansing of Uganda's Indian minority. Some 80,000 were expelled, leading about 25,000 to settle in the United Kingdom.

It is quite disgusting to me as an Indian person that you would justify the further victimization of my people, after the British victimized them. And you are supposed to be an ally?

A bernie bro throwaway. How quaint. Totally not obvious.

You should have apologized for calling me a Bernie bro after you found out that you were wrong.
