Sorry, but Ishtar and Semiramis are one and the same, and Tammuz was her illegitimate son. The “virgin birth” was a ruse to keep from being stoned to death for showing up pregnant after the death of her husband, NMRD, at the hands of Shem.
Yes, she definitely was a harlot, and soon after her death she became known by the pagan priests as Mother of God, and Queen of Heaven. This is the basis of the “goddess and god” worship of modern pagans (Ishtar and Tammuz).
Ishtar and Semiaramis are one and the same? Well, the briefest “biography” of each bear little resemblance to each other. But then Semiaramis doesn’t get you any closer to what you said about the Virgin Mother of God, either, since
1. Zoroaster, Semiaramis’ son, is not a God, so she certainly was never called, “Mother of God.”
2. Semiaramis is unrelated to Tammuz or Nimrod.
3. You seem to confuse “virgin birth” with “asexual reproduction.” I’m totally unaware of this passage you cite about avoiding being stoned to death for having a child after Nimrod’s death, aside from Googling it and finding other anti-Catholic websites. But since she had Zoroaster by her husband while her husband was alive, she certainly could attempt no ruse at being a virgin.
You’re apparently reading material from sources who just make up anti-Catholic fairy tales. You haven’t written one sentence which corresponds to anything about Semiaramis, Tammuz, Nimrod or Ashtarte. Nor are you explaining your deviances from mainstream sources; you’re just adding further, nonsensical statements which offer no explanation.
(To be clear, Wikipedia does reference Hislop, your apparent ultimate source, but only parenthetically, and with no bearing to any of its other information.)
