Sigh. Your complaints are legitimate, as far as they go. And let me tell you why some people won't come to your door:
We've had many wonderful neighbors in the 30 years we've been in our house.
We've also had three families who were terrors. One had two dogs that barked for up to 20 hours a day. They laughed in our face the first time we asked nicely if they could address the issue. A couple of weeks later, they threatened my mild and gentle husband with a shotgun and arrest for trespassing (he had knocked on their front door), and when we finally complained (ineffectually) to county animal control, they made up stories about our insanity, and our mailbox was destroyed several times over the next three months. Until they divorced and moved, then life became pleasant again.
A family on the other side of our driveway for a couple of years collected dogs, had four in a tiny run. They fought, barked frequently day and night, created clouds of dust and noise whenever we walked past them to get to our mailbox. The neighbors dumped trash and oil on our property (I caught them once). They spoke to us with barely-contained rage when we asked them if they could move their dogs away from our driveway (they had 60 acres). After our request and a follow-up complaint to Animal Control, the whole thing escalated, which I didn't believe possible. I think they stirred the dogs up at every opportunity, more peculiar junk was found on our property, and our garbage cans routinely spilled on collection days. They were finally evicted, and the family that followed are fine neighbors.
There's no way we can know who's a jerk and who isn't until we make contact. I'm glad you're not. But you can understand why I probably won't make that assumption about a neighbor who doesn't appear to be living up to neighborhood standards.
