You need to take the bad with the good, otherwise you'll never understand how far we've come. We hold on to slavery to remind us what it took, how efforts were not in vain, and to continue work on pushing for the things we believe in. We are here today because of the hardships we have endured yesterday. It's not "white guilt", it's to remind the world that slavery is bad no matter who does it, to teach us what it looks like, and that we all benefit from eliminating slavery, no matter the form it takes.

When we forget those things, we have things like the anti-vacc movement. People who have their own beliefs that fly in the face of reality, who've never had the experiences first hand, and to bend the notion of what is good. It rewrites the legacy of people's efforts, obscures the lessons used to fight, and trivializes the problems of the time. It manipulates both people and purpose and turns it against each.

My own opinion: Nobody feels guilty about slavery. There are only those that feel regret it's not still around.
