2-If such Marriage was Strange, then why didn't the Disbelievers of Quraish use it as a Pretext against Muhammad (peace and blessings of Allah be upon him)؟

those people competed in writing about such marriage and ignored the similar cases in the era where prophet muhammad was living.   why didn't the people - who criticized the prophet for marrying aisha- criticize the disbelievers who fought muhammad   and tried to kill him? they have married girls in early ages and even preceded the prophet – peace be upon him – in doing the same. so, if the intention of such criticizers is to criticize the relation between an old man and a young girl, they should have then spoken about the other similar cases which happened in the era of the prophet – peace be upon him.
