For the record: I don't care—well, actually, I do care very much, so let me start again. Whatever the situation, whatever we may dislike or regret, Joe Biden is our duly-sworn-in president and as such must be accorded the respect due that office. Detest and decry his policies all you want, but speak with respect. And if you pray, pray for him!
Also for the record: This is a non-partisan stance. I said the same thing about Donald Trump. And our previous presidents.
When Saint Paul urged Christians to pay "respect to whom respect is due" he was talking about governing authorities, and he was writing to Romans in the time of the Emperor Nero. If he can say that about such an emperor (who later beheaded him), I think we can manage a little basic courtesy now.
