That they would even have that type of practice shows what lengths they will go to force Mormonism on people Don’t ever be polite to the Missionaries unless you want to move without leaving a forwarding address. They will hound you and keep sending them to your home. They are very pushy.
Cults are like that. All of them.
The last time the Mormon missionaries came to our door, I invited them back for dinner (those boys live on Top Ramen), and had a captive audience to witness to them for 2 hours afterwards since they schedule the whole evening and are too polite to leave.
After that they crossed the street rather than walk by my house for a couple of years.
