I have showdead on, which is why I was able to see the comment.

There's advocating genocide, and shooting people on sight in an older comment.

I understand you're not the person that killed the comment, but could the commenter have expressed either of those points of view in a way that wouldn't have resulted in them being removed? If not, I think that's unfortunate. We're adults here and should be able to handle genuine conversation on sensitive topics, I would hope.
