A few questions:

How well did British colonisation work out for Native Americans? That would be a more fitting comparison to make. Look at life in the reservations.

Did the Romans meddle in British affairs after they were booted from the isles? How was life in the British isles in the aftermath (let's be generous and give them 100 years) of Roman colonisation for the common people?

Singapore is an interesting, and exceptional case. But also worth noting that even here, the economically and politically dominant Chinese Singaporeans supplanted indigenous Malays. The Chinese mostly arrived during the British colonial period.

People who espouse this sort of thinking also say similar things about South Africa. "Apartheid ended almost 30 years ago. You should be over it." Or that Black Americans - people who were only accorded full civil rights in the 60s - should get over centuries of domination since it's "already" been a couple of generations since they could vote and sit at the front on a bus. I could keep going.
