I can deal with mine just fine. I don't need to deal with that of some stranger anymore than I want someone sneezing on me. Having a small amount of gray water dump by accident is not going to kill a tree or a human but I think the issue with most here is the intentional dumping of large amounts of gray or any black in a location where it should not be dumped, like along a road. And BTW, if you have ever left gray water in a tank for an extended period you know that it can be more obnoxious than black. We usually treat the black tank.
