I don't think this is necessarily true. We have had similarly disputed election results in the past, like the corrupt bargain of 1824, or the compromise of 1876

I don't think this is necessarily true. We have had similarly disputed election results in the past, like the corrupt bargain of 1824, or the compromise of 1876. It's more of an annoyed grumble about the "stolen election" rather than a hysterical battle cry. And while I'm at it, let's not pretend like it's just the right that does this stuff. I seem to recall 4 shrill years of people freaking out about how Russia hacked the election (which turned out to be a big nothing burger). Wasn't this just as damaging to democracy? I think at the end of the day idiots will be idiots, and I'm not too concerned about a bunch of idiots complaining about the election they lost.
