There's a list of these that we might as well get over and done with now.
To be clear, this is not intended as "bashing". Having grown up in Delaware, I'm probably more familiar with the details of Joe Biden's career history than many DUers, who are going to be perpetually surprised by de-contextualized episodes going back to the early 1970's.
So, in order to prevent you from being surprised, let's wade into the Great Flag Burning Foofaraw Of 1989.

Biden proposes flag bill amid questions
WASHINGTON -- Senators searching for a way out of the emotional and political quagmire of what to do about flag desecration Tuesday proposed a new bill to ban the act, but legal scholars and some lawmakers quickly differed over whether the plan could do the job.
That's right, Joe Biden was the principal author and sponsor of a bill to make it illegal to desecrate the US flag.
Wrap your head around that, shake your demons out, do your poutrage dance over free speech, but that's the simple fact.
Now, you want to know the context?
In 1989, during the reign of Dear Leader St. Ronnie of Raygun, the Supreme Court decided Texas v. Johnson:
https://en.wikipedia.org/wiki/Texas_v._Johnson
Texas v. Johnson, 491 U.S. 397 (1989), was a decision by the Supreme Court of the United States that invalidated prohibitions on desecrating the American flag enforced in 48 of the 50 states. Justice William Brennan wrote for a five-justice majority in holding that defendant Gregory Lee Johnson's act of flag burning was protected speech under the First Amendment to the United States Constitution.
The circumstances of this particular flag burning arose from a disorderly protest held during the 1984 GOP Convention, again nominating Dear Leader St. Ronnie as Supreme Figurehead of All That Is Holy.
And those librul, unelected, dictators in black robes on the Court said it was okay to burn a flag.
Mind you, there are all kinds of laws you can have against illegal burning of "stuff" in general. Heck, in most areas you can't burn leaves anymore. There are also all kinds of laws you can have against disorderly conduct, unsafe use of flammable materials, and so on.
But burning a flag? Heaven forfend. If someone is allowed to burn a flag - even their own flag on their own property or even a crayon drawing of a flag which they just rendered on their own piece of property - the country would crumble.
So, there began one of those idiotic wedge-issue crusades which, like all idiotic wedge-issue crusades, had utterly nothing to do with getting anything of consequence done that would affect people's lives, but would result in a Constitutional Amendment making an exception for flag burning.
So, Joe had this one all figured out. Joe believed that he could de-rail the campaign to amend the Constitution by claiming he'd come up with a "Constitutional" way to ban flag desecration as a form of political expression.
Yeppers, that was what he thought.
Years after the fact, I brought this up with him and told him that it was a surprisingly craven act on his part, and that he knew damn well that providing an equally unconstitutional statutory alternative to derail the amendment drive, instead of opposing the amendment drive head on was simply dishonest. His answer was to the general effect of sometimes you gotta do what you gotta do. He explained that his bill provided cover to vulnerable Congresscritters to say that they supported Joe's idiotic bill as an alternative to being soft on flag desecration. The point was, he explained, not to ever get the bill actually passed, but to provide a vehicle by which politicians needing to say "of course I oppose flag desecration" a reason not to get behind a Constitutional Amendment to that effect.
Anyway, it is a reasonable question to consider whether Joe was correct or incorrect in his assessment that pimping a clearly unconstitutional bill in order to provide political cover, instead of simply expecting elected officials to support freedom of speech. Ultimately, neither Joe's flag burning bill, nor the Amendment went anywhere, and I'm sure in Joe's mind that is one in the "win" column. If you win, does it matter how you win?
But, please, get ready for the great "Joe Biden Anti-First-Amendment Flag Desecration Bill" to be unearthed from the catacombs of the political context in which it died.
