Hello, this is my first day on the internet. No one would ever scrape up the rare edge cases to counter my generalization.

How about this:

I am ok with companies not being held to the same evidentiary standard, the same beyond-a-reasonable-doubt standard, that our legal system is. I am ok with companies firing abusers, harrassers, racists, other bad actors, without iron clad court cases. And I acknowledge that some mistakes will happen and people will be fired as a function of poorly considered zero-tolerence rules. But I would rather have that rare mistake versus being unable to fire the serial harrassers because they conveniently didn't do it in front of a camera and victim accounts aren't "proof".

Because what is the alternative? No one can be fired without a trial and hearing or mediation of some kind? A fired employee can expect compensation for being let go for any reason? We are talking about a 180 from our current culture, colliding with not only free speech, but freedom of association and property rights.

Use that lovely freedom of speech to campaign against the stupid school rule that fired the security guard.
