Thanks for your comments.
Fly320s, I didn't notice the bumper stickers until after I let them into the vacant apartment they were to work in. When one of them came down later, I noticed that his hair was extremely short, just short of being shaved. They are young, skinny white dudes, and I think they are both blond, like myself. For what it's worth, I am a blue-haired, blond-eyed,
short-haired, light-skinned fellow myself, but my hair is not THAT short.
Mannlicher, I could ask them, but I think it will be best not to stir up anything.
ilbob, I'm letting them work, and I expect they will just do their jobs and leave. They are working in an empty apartment where they shouldn't have much contact with residents. However, this is a Jewish part of town (and I suspect they know that), and more than half of my residents are Jewish or Black. It's bad enough they have these bumper stickers that make me suspicious.
Thanks, Sindawe. La Raza would be less of a problem, just because they don't have such a bad public image. And because I have so many Jews living here. I have plenty of Hispanic workers doing jobs out here, but haven't seen any La Raza stickers yet.
