I don't like those face covers either... but you know, if you do something, all it will do is land you in trouble with that law. At least, that's the way I see it. I agree, it has no place in this country, it, some of the dressing as far as I'm concerned should be banned.
I was once at a McDonald's and this was sort of a racial incident, I won't even say which race did what, but a youth, one color, almost intentionally, let the door shut on a middle aged woman, the other color walking in. I thought that was so rude and it upset me. I still remember it.
We all have a boiling point, so, I certainly don't hold myself out as an example as to how to behave. I'm just saying, I'd try to keep my cool.
