Not necessarily them personally but previous generations of British colonialism really (deliberately) screwed over the indigenous people in my country in a multitude of ways.

Every descendant generation since has benefitted from that to the detriment of indigenous generations. I, and my children, benefit from it daily with superior schooling, housing, health, wealth, etc.

Even the smallest things (e.g. voting for progressive government, volunteering, learning the language and culture, advocacy) that I can do to helps mitigate some of that harm.
