What I said was "A spoofy but sincere ceremony with druids, witches, elves and giant kittens."
Notice "spoofy" and "elves and giant kittens." Not Pentacles, Crucifixes or Tallit.
As in a bit of dressing up fun.
Circle ceremonies are used by people of any faith and none.
Circlework is an efficient toolkit for creating a ceremony and can be used by anyone.
If you can accept the concept of north, south, east and west, you can use Circlework.
Circlework did originate among Pagans. Easter eggs derive from Christianity, and older religions before that. Most British children who eat their chocolate either don't know the connection or don't care about it, nor do they need to. Both the chocolate egg and the Circle do their job of providing pleasure and fun without need for theology.
I understand somewhat your jumping to hasty assumptions. Ignorance is not shameful.
I do not understand your rudeness. If you think something is inappropriate then say so straightforwardly within the bounds of courtesy. Then it can be accepted as a valid critique, or as in this case the mistake explained.
