Question to the pagans.
Your gods’ temples and scared places have crumbled to dust and are forgotten.
Really? The Parthenon’s been forgotten? How about the temple of Apollo at Delphi? True, there’s not much left of them, but remnants have survived, and archaeologists dig up temples every day. In recent months, a temple to Demeter and Persephone was unearthed (they built a monastery on top of it). Even places that don’t have physical sites haven’t been forgotten.
Your gods’ priests and followers are but faint specks in history.
Enheduanna (one of the first published authors, also a priestess of Sin who also wrote hymns to Inanna), Sappho, Pythagoras (who gives his name to the Pythagorean theorem), Alexander the Great, Flavius Claudius Julianus Augustus (A.K.A. Julian the Apostate), and that’s just a tiny sample of the Pagans who have shaped history, to say nothing of legendary figures like Boadicea (who sacked London), Sigrid the Proud (who was called a “heathen b*tch” and decided to call off her marriage to a Christian king…and raise an army against him), Radbod of Frisia (who refused to convert to Christianity because he: “would rather be in Hel with his ancestors than in Heaven with a passel of beggars”). I wonder if Alexander the Great in particular would appreciate being called a “faint speck in history”?
Your gods have been reduced to comic book characters.
The Bible has been made into graphic novel and manga format, you know? I actually
like an anime that’s based off of Norse mythology. There’s a video game series (Shin Megami Tensei and the Persona series) I play in which Jesus, Lucifer, and Mary exist side by side with the gods. (I actually keep Lucifer/Helel in my party because he’s quite powerful).
Why would you worship such weak and flaccid beings?
I have to laugh at the way you describe my gods as ‘flaccid’. Freyr’s cult statues often had an erect phallus. It strikes me as a very appropriate descriptor.

That said, the gods have survived in the names for the days of the week, in the expressions we use every day, we even name companies after them. I would say that the fact that the gods survived even after attempts were made to wipe them from memory is not a sign of weakness, but strength.
If you can control the material world, then create gold, platinum and gems out of nothing and make me wealthy beyond my imagination.
Why would I make you rich when I could just make me rich and give you some of the money?
Seriously though, magic (as many witches practice it) doesn’t work that way, that’s TV magic. TV magic isn’t real. I’m not a witch and even I know that. (I see magic as more of a psychological phenomenon, others believe in it in a more literal sense).
If you can control men’s minds, then make Scarlett Johannson fall madly in love with me.
First of all, many witches (particularly of the Wiccan variety) would never use magic to manipulate another person. If Scarlett Johannson fell in love with you due to a spell, would it really be love? No, because the spell would be compelling her to love you. That is absolutely unethical. Now, it’s worth noting that some traditions (particularly those derived from the African diaspora) don’t have a problem with such magic, but I expect the opinions of individual practitioners vary.
However, even assuming that I was a witch who wouldn’t have an ethical problem and that the magic I perform actually works (instead of just being a psychological “crutch” of sorts). Think of how many people who would be after the same goal as you. How many Scarlett Johansson fanboys (and, quite possibly, fangirls) daydream about having sex with her/marrying her/having children with her? In that case, their intent is working against yours, and that’s a lot of intent. It’s also why the “Why don’t you cast a spell to win the lottery?” deal doesn’t work, almost
everyone wants to win the lottery, and pitting your will against the entire collective will of North America isn’t a good idea.
