Hahahaha. No, you don't know what you're talking about. Listen to Ben's podcast or Steven Crowder's podcast. You'll realize its the other side doing what you are describing.What does the left have to do with my opinion of Ben Shapiro?
^ this paragraph pretty much explains it.
Even in a limited world where you believe gender is binary and separated into male and female, it's a total shithead move to call someone the wrong gender. If you don't want to get into calling people "xem" or something then whatever but that example rarely ever comes up in real life anyway.
Misgendering someone when you know what they prefer is just straight-up bullying, and there are few ways to respond to bullying unless the bullying is recognised for what it is. It's equivalent of someone giving someone a pet name they really don't want, and repeating it over and over even when asked to stop.
If it happened once, you might not think much of it and any insult perceived wouldn't really be that justified. But if you harassed that same person the same way over and over, and they endured it regularly to the point it became systematic bullying endured from many of their peers, in many social contexts, you'd probably understand why they were upset.
And yeah, nowhere am I condoning someone being violent and threatening someone like that - but if you watch that altercation (it's on YouTube somewhere) it becomes obvious who the real shithead provoking who is there, and why she person responds the way she does.
Ben Shapiro, and the people who follow him are more often than not quite hostile and malicious towards basically anything they don't understand - namely people from already repressed minority groups that are regularly bullied and socially stigmatised.
