Maybe it depends on where you live. I live in Wyoming, and there are a lot of LDS people here, and they are forever going door to door, more so than the JW's do. Probably different churches have different philosophies, but the LDS people here are BIG on door to door "witnessing".

I HATE it when people ring my door bell and try to convert me. HATE it. But, in all fairness, I hate it when ANYone rings my door bell and tries to sell me something ... be it a vacuum cleaner, a magazine subscription, or their religion. I find it incredibly rude.
