On the flip, shouldn't we all be willing to accept that some of the things we think can't be true are true? History has all kinds of examples.
Arguing that's it's other people who are really making this mistake makes no sense because you made the arg.
Still looking for the cite on "the definition of per-capita".
This is using images of a senator's children and proposing a hypothetical rape of them in service of a political goal, which is so blindingly reprehensible that it's hard to even type out: https://twitter.com/ChristiChat/status/826182267978407936.
Everything you said is also true of Hitler comparisons – anyone with the resources to make that allegation can make them. The only argument I've made is that valid counterexamples exist to your claim that the left is an "order of magnitude worse". Asserting this is not judging individuals by their actions. This is demonizing a large group that you have defined, based upon on equally-hackable individual actions you have observed.
There is no credible evidence of your assertion that the left is somehow rhetorically worse. That's the only claim I'm making: that the hypocrisy is not provably asymmetric. I have not outlined a personal standard of evidence.
But further than that: I've seen persistent allegations and slurs against the Jewish faith (many in pre-prepared image form), advocation of literal genocide, celebration of alleged bills that would make it legal for people to use motor vehicles to strike and kill protestors, and calls for those protesting legally and peacefully to literally be rounded up and imprisoned by police because a small group of unrelated individuals committed acts of vandalism or violence. The excuse? "If they're not stopping them, they're supporting them". These were not isolated incidents. I personally witnessed hundreds of voices repeating the latter talking point on a single local news station's Facebook page, in a single night.
The current US National Security advisor Michael Flynn allegedly accidentally retweeted one of these. According to news reports, it read "Not anymore, Jews".
Further down the abyss, speaking more to rhetorical depravity: I've watched pro-Trump posters in private Facebook groups post pictures of themselves pointing firearms at the camera in response to disagreements over fact. There was also a disturbing pattern of posters sifting through the public profiles of others for pictures – essentially peoples' family photos – altering them to appear pornographic or otherwise offensive, and then reposting them in public. One even literally offered to sell a stranger's child in to slavery, on their personal Facebook page, using a picture of them, "because that's what the Muslims would do". I saw attempts to get people fired from their job due to a Facebook political disagreement.
I really believe that there are intrinsic issues with social media that are feeding this crisis: a demand for instantaneous engagement often at the expense of even a few minutes of thought, a "real names" policy on Facebook that sabotages efforts to deflect/prohibit personal attacks in discussion groups, a comically understaffed/underresourced reporting system that I've seen people on all sides try to weaponize against those that disagree with them, algorithmic news feeds that people have voluntarily handed over their information-seeking ability to, and notifications that allow asynchronous debate to escalate into what people perceive as intrusive interruptions. Many unfortunately don't know how to turn these off, and react in anger.
It's no way to communicate and no way to live.
