I shared a very personal post a few month ago and then unlisted it from my site. It's a tough one and I was very worried about attracting the wrong folks with it or getting into painful discussions. But a lot of really wonderful conversations followed. Especially with people from the US.
I think it's the right time to post it once more. Maybe it can help you in some way or another: "My Grandpa was a Nazi" https://bastianallgeier.com/notes/grandpa
