Fairly ridiculous behavior, clearly violently threatening. Had he made one solid "move" against you ...
Bully, definitely. He's going to meet someone who won't tolerate being victimized, at some point. Even if it kills him. Hopefully he'll wake up before then. If not ... then, not. It's all on him.
Kudos for being capable of withholding a solid halting of him, to terminate the violence. The only thing that didn't "save" him is he didn't follow through with it.
It is everywhere, these days. People have largely had enough of being "pushed" around, having little say, being told what to do, etc. Far too many are lashing out, now, even with deadly violence. It's pitiful, and sad. I get that sort of treatment from drivers of vehicles on a weekly basis, when driving my own car. For no other reason that that: they're there, and ticked, and wanting to lash out at anybody who's there.
