I never let my wife or kids open the door for unknown visitors and I don't care if it's weird. Anyone is allowed to come on your property and you aren't allowed to harm them. If you ask them to leave and they don't then they are trespassing. You still can't harm them though. The laws in the US vary by state, some aren't like what I described above. If a cop comes to the door I step outside to talk to them. It's a dumb move to let them inside. And yeah I don't like the way I act in these scenarios but it is the safes/smartest and I agree with the title of the thread in this regard.

And if someone of reasonable physical size puts their foot in my door as I open it a few inches to talk to them, they will get the door slammed on it and we'll be calling in a home invasion pretty fast.
