These are all very good answers.
I'm not actually trying to discourage them from coming to my door. The posters on Reddit believed that their over the top theatrics were capable of frightening various religious door-knockers away.
The question isn't really asking advice about keeping them away. I only have to open my mouth and they'll usually scarper đ. (Although admittedly the last time I wasn't feeling it and politely said "No thanks" and closed the door slowly.)
It's more: did anything the householder did to try and frighten you away actually frighten you away? For example (from the Reddit post), you knock on the door and it is answered by someone pretending that they are about to offer up a black mass and you are their sacrifice. Do you freak out or do you roll your eyes and bid them a good day as you walk calmly away*?
I'm genuinely interested in how centred you all were when you were in. I doubt that any exes here were frightened bunnies who fled at the mere mention of the word "Wiccan". Or that someone in minimal clothing would freak you out.
Didn't you used to have meetings where you would roleplay various scenarios for practice? Did they cover difficult contacts and people who were obviously trolling?
*Obviously if they're wielding a knife in a threatening manner, it's different than if someone is just trying to trigger you with BS that they think must scare you.
