Yes, that is how Christians think of it. And by the same token, Muslims view their crescent in the same light.
Do you? Would you accept this from Muslims? If not, why do you demand special treatment from others for you?
What did I demand? I think it would be wrong not to give worship space to Jews, Christians, Muslims, or any other legitimate religion. I don’t think Wiccans is a legitimate religion, but even so, just as a matter of social justice, if they were given a space for the purposes I do not begin to comprehend, that should have been respected.
I was asked if placing a crucifix on the doorstep of a synagogue is hate speech, and I answered that it is not: the one doing it has no hate. Or at least, judging by the meaning of the symbol alone you cannot discern hate. Would it be a good neighborly act to do so — perhaps not. This is why Christians generally don’t do such things.
The Crescent is a symbol of Islam, but it has no meaning of salvation or goodwill. It is not like Mohammed’s life has a crescent figuring in it. To many it reminds of the Turkish saber. Whereas with the Cross, the meaning is in the symbol. What is it? - An instrument of torture. - Who was tortured? - Jesus Christ. - Why? - Cuz he loved everybody.
More on the Wiccans though: the difference is that theirs is an activity that is inherently anti-somebody. While followers of legitimate religions seek the truth, those folks seek to break what others found. I would not tolerate them anywhere, if I were in charge.
