From what I gather, all this happened after a couple was kissing in line at this restaurant in Santa Monica. That's just what other video descriptions have said. I have not verified that.
But what we do know is that this woman likes to escalate sh*t at an outrageous scale. This is an exercise in patience. You can choose to feed the fire, but everything you say will be used as fuel for their delusional hate. Without fuel, it will burn itself out much faster.
Or you can chose to tell that fire to f*ck off and see where that gets you ;)
