You identified one of the primary characteristics of a mansplainer: the refusal to ever let go of anything, a mortal fear of not getting the last word. It’s a dead giveaway.
Also, I’m fascinated by the eagerness to attach their anger about Ossoff loing to Pelosi who had no involvement with his campaign and whose job descrption has nothing to do with winning elections, special or otherwise. I keep pointing out that the correct person to blame—if they need to fly into a rage that Democrats aren’t sweeping virtually unwinnable races in seats long held by Republicans — is Ben Ray Lujan, the chair of the DCCC. But then, they woudn’t have the opportunity to let their latent misogyny emerge.
