You're misunderstanding what was said about that subject.
Egregious religious or political statements should be removed because they derail the conversation.
Examples of benign religious statements that generally do not incite an all out religious discussion include: “Bless you all”, “Namaste” or “Merry Christmas!”, etc.
“The right wing Christian conservative zealots need to shut up” or “Those woke lib shitheads will get their own in the end” should be removed.
In other words, a benign Holiday statement is okay. As opposed to the other two examples, which are not, should be removed.
