The notion that Mahomet had many wives and married a 9 year old cannot be ascertained by historians. These are here hearsays written by arabs 200 years after mahomet's death and when arabs themselves wanted to create their own religion, " islam" by introducing the hadith and sunnahs which cannot be corroborated.
Your views are unique but they do not represent mainstream islamic beliefs. To be a moslem, you have to acknowledge that mahomet was a 'prophet' and believe that the quran and the hadiths are real revelations.
