With the onset of puberty the physical and mental changes in the female have reached a new stage of development. It is however evidently plain to the unbiased observer that the physiological and mental development of the female cannot have reached a stage at the onset of puberty where it could be said that the female is ready for marriage. This is just a plain fact that is evident to all that it is impossible for a female of nine years of age to have reached the end of her growth process, both physically and mentally. She is just reaching a new stage. It is a law of nature. One which Mohammed broke.
To me this is another disturbing and dangerous facet of Islam which just shows how desperate it is to rule regardless of the consequences in terms of ruined lives.
