So an incident that happened in the past is not history. I hope you don't teach history, since history is a study of things that happened in the past.
And to clarify I didn't go looking for more incidents, someone said Biden's threat of violence was in response to Trump's incivility and there was no history, except there is and you seem to think that something that happened in the past is not history.
Oh, and I also appreciate you putting things in quotes after my name to indicate that you were quoting me, except I didn't say or write it. Once more your academic credentials are called into question. Not sure what grade you teach, but you do require your students to cite properly and not to attribute to someone something they didn't say. Now if you wanted to indicate you believe that that quote summed up my position, you could do that in a manner that would be correct. That is if you learned how to summarize someone position from what you read rather than reading into it. It is know as exegesis vs eisegesis. I know you have master eisegesis. And yes I am being sarcastic.
You were responding to OAM, but . . . .
I think that the "quotation" that OAM did falls under the category of satire. I've seen that construction used by other posters on this board.
History is not incidents that happened in the past. It is the study of those incidents.
It's sort of like the military's distinction between information and intelligence. Information is just random stuff. Intelligence is the product of analyzing information for its probable truth, it's significance, etc. History is the analysis of what happened in the past using what sources we have for those events. And you never have enough sources that are reliable enough, so you are always making a choice as to whether or how an event happened, and as to whether it is significant or not.
The casual term "a history" as in the question to which you responded just meant "does he do this often?" Citing one example does not really prove that he does.
For example, "Does Joe Biden have a history of misstatements and/or embarrassing statements?" The answer would be that, yes he does, and you could cite his plagiarized campaign biography from the '80s, his claims to have graduated at the top of his law school class, his statement about Barack Obama being "a clean negro who speaks articulately" (or words to that effect), him telling a guy he wanted to recognize to stand up when he was in a wheelchair, and on and on and on. He's a gaffe machine.
Does he have a history of threatening to whip people's asses? He's done it more than once, I'm pretty sure.
IMO, Biden is no great candidate. He's flamed out in every national race he has been in and he may well flame out this one too. He is sometimes called the wise old head in the Democratic Party, but he strikes me as the village idiot. I thought that he was dumber than everybody's favorite whipping girl Sarah Palin in 2008, and that's a low bar to get under.
But he's not, IMO, nearly as awful as Donald J. Trump, who is our worst President since Andrew Johnson. if not our worst ever.
