I couldn't agree with this more.
It also just happens to be to their benefit when the bare principle is decontextualized because then they don't have any personal responsibilities on the matter.
Could you expound more on what you think a person of today's personal responsibilities on the matter are aside from not being a racist and correcting racism where it truly exists?
Do you think there is more that should be laid upon the shoulders of people today for what happened in the past? ( just assume the people we are talking about are not racists today, otherwise they would have to correct and deal with what they heap upon their own shoulders.)
