Simply because a door is open, doesn't mean one ought to walk through it.
That is a silly comment. There are safe zone threads, called "caucus" threads where you can post without interruption or dissent. Any open thread is posting in the town square for discussion. Not everyone will agree with you. Open threads are for discussion.
From the Religion Moderator's home page:
Open threads are in a town square format.Antagonism though not encouraged, should be expected
Posters may argue for or against beliefs, deities, religious authorities, etc. They may tear down other’s beliefs. They may ridicule. “Open” RF debate is often contentious.
It requires thick skin. A poster must be able to make his points while standing his ground, suffering adverse remarks about his beliefs - or letting them roll off his back. Members of religions which are as much culture as belief sometimes take religious debate personally. If you keep getting your feelings hurt because other posters ridicule or disapprove or hate what you hold dear, then you are too thin-skinned to be involved in “open” RF debate. You should IGNORE “open” RF threads altogether and instead post to RF threads labeled “prayer” “devotional” “caucus” or “ecumenical.”
