Saw some news thing had a site where you could look up who had a nazi party registration in your family and some nonsense about guilt from the past and I cannot stress enough:
People in the past were bad.
They weren't you.
You are not magically a bad person because a bad person contributed genetic material to you.
What you do matters. Who bred you does not, at least it sure as fuck shouldn't, and doesn't to anyone who isn't an asshole.
