I appreciate your consistency. As for when the missionaries first came to me, I felt fine. Not annoyed, not bothered, not intruded upon. Actually, I welcomed them. I’ve had sales people, political candidates and Jehovahs Witnesses knock on my door before I became “Mormon.” I didn’t find it rude then or now. My current view is not formed by my current religion but perhaps more from being a door knocker myself for over 30 years (which is considerably longer than I’ve been Mormon.) (And maybe because I was happy the missionaries came to my door as I wanted to talk to them!). And maybe people in the UK view it differently than the USA because I would say the majority that I know don’t generally mind. They understand why you’re there. A lot of them are happy to take the opportunity to talk. I’ve met quite a few be annoyed if we didn’t knock on their door! Like me, if they are busy they say go away. Now, if you didn’t then politely say goodbye and leave, that they wouldn’t like. Or maybe they are too polite to say they don’t like it. But I’ve had conversations with a lot of folks about it and most of them did not say they didn’t like it or that people shouldn’t do it. Of course there are those who don’t like it, as you don’t. So put a notice on your door (or a doormat outside it) and most uninvited callers should be polite enough to leave without knocking. Because if someone clearly doesn’t want a canvasser or missionary or anyone else to knock uninvited, I agree it would be rude to proceed to knock. I’ve walked away from the occasional door because of a notice. You have your experience and I have mine. Both true for the areas we know and both purely anecdotal. I don’t see how you can draw any conclusion about what most think unless there is some empirical, objective evidence and even then, feelings about it may vary from country to country, dependent on culture. In the end both of us, any of us, can only speak for our experience in a limited area of the world and not for most of the world.
