Sure Jan, they can just shrug off close to a 100 years of colonization like it never happened. It's not even been 100 years since it officially ended.
- India had been practicing slavery since immemorial times [1]
- Then, the British started ruling the place and after only 2 years in power they abolished slavery in all parts of India they controlled [2]
- Then the British left, slavery returned to India, and it's somehow the fault of the British it still exists.
This sums up quite nicely your argument, right?
