Again, you said women have to have kids as soon as possible and I am pointing out that Aisha having not started her period was incapable of having kids..so the prophet's marrying her has nothing to do with makong sure she had kids early

I am glad you asked why Aisha made that statement and I will show you the full Hadith below,

"Narrated `Ikrima:

Rifa`a divorced his wife whereupon `AbdurRahman bin Az-Zubair Al-Qurazi married her. `Aisha said that the lady (came), wearing a green veil (and complained to her (Aisha) of her husband and showed her a green spot on her skin caused by beating). It was the habit of ladies to support each other, so when Allah's Messenger (ﷺ) came, `Aisha said, "I have not seen any woman suffering as much as the believing women. Look! Her skin is greener than her clothes!" When `AbdurRahman heard that his wife had gone to the Prophet, he came with his two sons from another wife. She said, "By Allah! I have done no wrong to him but he is impotent and is as useless to me as this," holding and showing the fringe of her garment, `Abdur-Rahman said, "By Allah, O Allah's Messenger (ﷺ)! She has told a lie! I am very strong and can satisfy her but she is disobedient and wants to go back to Rifa`a." Allah's Messenger (ﷺ) said, to her, "If that is your intention, then know that it is unlawful for you to remarry Rifa`a unless `Abdur-Rahman has had sexual intercourse with you." Then the Prophet (ﷺ) saw two boys with `Abdur- Rahman and asked (him), "Are these your sons?" On that `AbdurRahman said, "Yes." The Prophet (ﷺ) said, "You claim what you claim (i.e.. that he is impotent)? But by Allah, these boys resemble him as a crow resembles a crow,"

(Sahih Bukhari 5825)

So you initially said that a woman can easily leave an abusive relationship and that it is strictly forbidden to mistreat women in Islam.

A woman in the above Hadith was beaten so badly that her skin turned green, this is why Aisha made that statement that she had not seem women suffering as much as Muslim women. And the poor woman came to Muhammad to report the matter...

What did your prophet say? That this woman has to allow this same husband that has been beating her (not explaining or traveling as you earlier claimed) till her skin turned greener than her clothes, to have sex with her before she could return to her previous husband.

And No, let us finish discussing how Islam promotes and empowers women's rights before we can talk about Christianity.
