So scrolling through these replies it seems like your main issue is with the word "Bitch" and nothing else about the sentence. Specifically saying "word choice matters".

I'd agree that bitch was a previously gender-based insult. Key word is "previously". While it can be used in a sexist context, so can almost any insult. I'd say it's no more gendered and no more sexist than insults such as "dick". Language is alive and as such it changes over time.

Imbecile, moron, idiot - these are all words that in their original context and with their original meanings could be considered highly offensive. Yet they're totally PC now. Not exactly polite, but not politically incorrect.

Through common use and their context being less to harm specific individuals and more just as a general insult these words changed into what we know today.

If it was a male dancing on desks that got knocked over the sentence would remain contextually appropriate. But you would no longer be able to call it sexist. See how there's a failure in logic there?

As it stands with the video itself the violence was a bit overboard, I'll admit. But having been in situations where very loud very annoying people suddenly invade my personal space in a blatant manner like that, I'm betting that person just reflexively overreacted. This isn't really "violence against women" so much as "violence where a woman happens to be involved". She's not being attacked because she's a woman, and honestly I'd expect the same outcome if it was a dude as that person dancing was most definitely provoking a confrontation. It's akin to saying that a deployed female combatant being under fire is "violence against women". The situation is a violent one, the soldier being female has nothing to do with it.
