That is wrong. I know what they are talking about and it is false. This is the first time I've seen that story written this way and blah

Zeus raped his daughter Persephone in a cave while being in dragon or snake form. This is how most say Zagreas was born. Her child did not get to live long but Zeus swallowed Zagreas heart and later spat out Dionysos.

He did this one more time later before her kidnapping also 

Though many debate that this was actually true and is conflicted
Some say Zeus raped her and others say she had no children at all. I do know for a fact she was raped. They said Persephone held a beauty like Aphrodite which is why those two butt heads a lot. Which is what caused her the mess with the horn dog in the first place.   

I did say she had gods trying to woo her but Demeter pushed them away as best she could and hid/over protected her daughter. Demeter never expected Zeus to pull trickery
