If the message of the art is to equate the sufferings of a modern feminist, or of “women” in general, with the sacrifice of Jesus, it is indeed blasphemy, a kind of self-worship.
Look up National Lampoon #21, “The Story of Jessica Christ”. The crucified feminist bit is very old (1971).
The early 1970’s feminists had already grown so obnoxious that NatLamp went after them instead of the usual targets, Richard Nixon & the Vietnam war.
“Germaine Spillane’s” crime novel “My Gun Is Cute” was another blowback at the Gloria Steinem crowd.
Anyway FWIW, “Christa” beats the heck out of “P*** Christ”.
Depicting the SON of God as a woman is blasphemy.
