Not all has-been losers are treated equally. The so-called leftist media has not taken up her claim; the democrat base has not taken up her claim; I've heard of no serious democratic candidates running on her claim. So when you say it isn't just one side, you're comparing a mountain to a molehill.
Hilary made jokes about it for sure. Trump sounded like he wasn’t joking. Maybe libs just can’t get his joking style.
Half of the country doesn’t trust the other half, and Vice versa. That’s mostly the problem right there (they trust their media but not the othersides, they trust their election officials but not the othersides, well, except in Georgia).
That’s just a straight up lie. Or—being charitable—a shameless false equivalence.
She repeated the (proven) fact that there was widespread Russian involvement in promoting her opposition & a disinformation campaign.
edit: note "Twitter files" showed that the claim of large Russian influence was unsubstantiated.
The Twitter Files showed zero of note, they were themselves an orchestrated propaganda exercise that suckered exactly who it was aimed at, but was widely—and deservedly—mocked in every other circle as completely unserious.
Hell, they destroyed what little reputation Matt Taibbi had left. Even he had to backtrack somewhat after the fact (in the most milquetoast, admit no actual fault, fashion tho I might add).
At most they revealed that the Twitter safety team did much more than they were credited for publicly, and revealed that most people have no idea what Trust & Safety involves.
As for “various definitions of proven” in this case the definition is “actually happened in reality and we have the receipts”, as in “proven fact”. Hell, people went to jail over it.
Partisanship is really annoying.
It's also worth considering it isn't even just one side, in 2019-2020 Hillary was still saying the election was stolen from her.
Note: I was working for an election services company over the 2020 election cycle and saw coworkers and even myself seeing death threats. I still think there were a lot of at least suspicious things across the country. In the end, the lack of trust in media/news and the government is pretty well deserved all around.
