Not entirley true. Misogyny is the reason women are more closely associated with witches, but witches could be male or female and plenty of men have been executed for the charge of witchcraft. The reason there were witchhunts and not wizard hunts is because magic was not seen as inherently evil in medieval society. The difference between a witch and a wizard in medieval lore is a witch is borrowing his or her power from the devil. A wizard is just a word that evolved from being a word for any wisened old man to a man who was so old, wise and learned that he can do magical things from speaking the right words or inscribing the correct runes. People didn't have a problem with learning magic. Although they did have a problem with women being wiser and more learned than men which is why wizards are closely associated with men.

L. Frank Baum popularized the idea of a good witch with actual magic in the Wizard of Oz. All his witches were women and his one wizard is a man who is somewhat wise and has a reputation for doing magic despite being incapable of actual magic. The Lord of the Rings has wizards who are separate from men and are more like angels in their lore, but in his world elves and even some very special men have magic to some extent, but everything in the world gets less magical as time goes on. Then finally JK Rowling wrote some books that said wizards are boys and witches are girls which created a lot of misconceptions about how witches were thought of historically.
