Is the practice “accepted”? Well, we may have gotten used to it. But it’s not “acceptable” behavior.
It’s gotten to the point where I dread opening the door. Some of the tzedakah collectors have gotten very aggressive, ringing the bell at all hours, arguing, etc. I try to remind myself that I’m glad I’m not in their position…but giving tzedakah happily becomes a lot more challenging when the recipient seems unappreciative.
