See that's what you don't get. It literally has nothing to do with Kavanaugh. The question is whether you want to live in a society where any person can be publicly harassed while eating dinner with friends or family at a public restaurant. I prefer not, but that's just me.
There is literally no chance that I will find myself in a position where I am the victim of that type of public harassment. But I don't want to see that behavior for the restaurant owner and employees, for the other patrons in the restaurant, for the subject of the harassment, or society in general. I think it's boorish, unintelligent, unprofessional, bad mannered behavior.
But I'm old. You guys apparently want to live in that world, and you're likely going to be around a lot longer than I will be, so good luck.
