Nonsense. Most of us would just like to be free of these annoying calls. When my brother in law was in the hospital near death, we felt we had to run pick up the phone, even if it meant getting out of the shower, leaving the dinner to dry on the stove, or running indoors to get it--imagine our chagrine when it wasn't an update on his health, but another &*%$#@!! telemarketer.
They have NO right to intrude on my life as they try to do. It has nothing to do with "saying no." I have no trouble with saying that. I just shouldn't have to interrupt my life every time someone wants to sell aluminum siding to insurance.
You can put up a No Trespasing/No Soliciting sign on your gate or door, but your telephone is nearly defenseless.
