Trading Down at 19?

Off topic, but not really. In this post there is a reference to a Senator and a SCOTUS nominee. Was/is there a warning? After all I got a scolding and points deducted while mentioning “Biden” in a comment. Maybe the mods can educate me?
While I see how it’s probably best to just avoid all unnecessary politics…I don’t think that it was a partisan comment, and that’s the variety that gets people into
trouble.
