Hmm, quick question, are you yourself Muslim? From what I can tell, I don't think so.
First of all, Muhammed wasn't a "rapist", "molester", or a "murderer". You are obviously mistaken. First of all, he never had sex with anyone outside of marriage. And by Muslim faith, that means, no more than 4 women. (The main reason for polygamy in Islam is intended for reproduction, but is STRICTLY [yes strictly] ruled that you must treat each one of them equally, and if you don't intentionally, that will get you closer to Hell. Next, the age of A'isha is still controversial, some say she WAS 6, others agree she was young, but not 6, but infact atleast 9 (rightful age of marriage in Islam [for females]). A'isha also wished to marry Muhammed, not him marry her. She always boasted to others about how she was his "best/favorite wife". Muhammed, told her that she wasn't, because she first of all, disobeyed anything he told her to do, and she was far from modest. Lastly, he was not a murderer. He did not kill for spite, and never initiated wars unless it was for defense. Arabian history books would concur.
(I don't like the fact that you question my faith just because I'm shi'a either)
Anyways, apostasy, in my opinion is bad. You simply cannot tell me I am wrong. Opinions cannot be wrong. And when I say "rejected" I mean as in being shunned.
