Just a comment on this point, I see two huge differences:
1) Gore conceded. On 13-Dec 2000. Trump only just "conceded", and still called it rigged, stolen etc. It makes a big difference when the leader concedes.
2) Technology has totally change the landscape in the last 20 years. There are now plenty of spaces on the Internet, huge echo chambers, allowing people to share posts and fuel each others hatred, spread misinformation, organise and mobilise.
2020 obviously blew it all out of the water though.
> You didn't see this sort of reaction in 2000
I think you found the reason? When exactly have we seen such a reaction before?
I think it's more accurate to say that a percentage of people believe they will benefit by repeating claims that the election was rigged.
It's difficult to truly believe that an election was rigged, by the other side, when your side was ultimately responsible for its administration.
In a mid December CBS news poll, “82% of Trump voters say they do not consider Mr. Biden[‘s win] legitimate.” The vast majority of trump voters isn’t the same thing as half the country.

Seems like most voters were still holding out while there was some hope of a viable legal route to contest the election. But a majority of Trump voters, at the time of the poll anyway, made a clean break from contesting the election after the electoral college vote.
And to be really fair, half of the country believed neither of those things. There are plenty of people who voted for Trump who believe that he lost fair and square, and ditto Hillary voters in the previous election.
You didn't see this sort of reaction in 2000, and that was far far closer.
And to be clear, this election was 306 to 232. That is considered a landslide in my book (meaning my 40+ years of living). And in percentages, you can see just how poorly Trump performed in this election - 51.4% to 46.9%. 2000 was 47.9% to 48.4% (technically a negative 0.5% difference).
So I think your argument is completely disingenuous.
