"SATANIC ANTICHRIST IMAGERY"
What do you think that this is still used by the Pope?
Commonly knowledge is that the Inverted Cross is a "trademark" of Saint Peter, one of the most revered figures in the Catholic Religion.(The upside down cross the an ancient symbol of St. Peter’s crucifixion.)
And it is still - until today - used by the Popes. (The Popes, being the successor of Peter, employ the symbol of the upside down cross as a symbolic reminder of St. Peter.)
An upside down crucifix, which seeks to invert and subvert it’s meaning, certainly might be used as a satanic symbol. But Satanists misinterpreted the meaning of the symbol by declaring its reversal to be the inversion of Christianity; the symbol was thus rendered useless to Christians.
