The lesson is that Reddit is not real life, and that calling half the country racist sexist fascist inbred stupid genocidal monsters turns out to not be a winning strategy.
Whether democrats finally learn that lesson is another thing. I am not optimistic on that.

The Democratic campaign did no such thing. Can you point to any examples? As far as I can see they went to great lengths to avoid saying anything like that.
As far as I can tell there was far more venom from the Republicans. Maybe the lesson is that a winning strategy is to be more insulting.
It was a single remark by the outgoing president who wasn't standing for election, and something he quickly rowed back on. It was clearly something he didn't intend to say, but at some point in an election campaign someone is going to misspeak.
Anyway, you're moving the goalposts. The allegation was "calling half the country racist sexist fascist inbred stupid genocidal monsters".
Meanwhile, Trump: "Crazy do-nothing democrats", "horrendous people", "the Dems are vicious"... and about 10,000 other insults whilst seizing on one offhand comment from Biden.
Biden said, "the only garbage I see floating out there is his supporters", in response to one of Trump's supporters saying Puerto Rico is garbage. Then Biden tried to walk it back by saying he meant that supporter, or his rhetoric, or whatever (and even if we deny him that walk-back, "supporters" is not all conservatives, all Republicans, or even everybody who votes Trump). Democrats mostly called this a gaffe.
While unacceptable by presidential standards, it's extremely tame compared to the things Trump regularly says about groups of people (we could even just limit that to the things he says about liberals or Democrats), and the vocal support he receives from his supporters for these statements. The fact that this got so much attention is evidence that "double standard" would be an understatement.

They don't (in general). Some of them over-apply those words. Some of them apply them to an over-broad category ("conservatives" or whatever). Some of them apply some of those words to some Trump supporters, which is not even the same thing as Trump voters, Republicans, or conservatives. And of that sub-sub-subset, sometimes the harsh words are even understandable, considering the hideous, immoral things they are being applied in response to.
Meanwhile, Trump supporters are much harsher with their words, and use much broader strokes when applying them.
I.e. it's the opposite. One of the defining characteristic (as opposed to simply a tendency) of the speaking style of Trump supporters is mockery and provocation and insulting and name-calling and threatening. They don't all do it, but it's an undeniable part of their ideology.
