But why do you have the urge to show a list of famous people? Can you not prove your point without this list, on your own? Why do you need the prop of other people's fame?
If fame of any person proves anything, then there are famous people in every religion and belief. I feel you should learn more about religion, not just Islam, but all religions, then you will be able to look at all different faiths and beliefs objectively.
Famous does not necessary reflect intelligence nor does it mean the choice is right. Islam should stand on its own credential. If the religion is true then its adherent should progress well economically, culturally, socially, sciences etc. However we hardly see any muslim countries with more than mediocre result for those areas. Is it because the adherent is weak or the religion is false.
I AM VERY OBJECTIVE WHEN I SAY THAT I OBSERVE THAT A LOT OF PEOPLE THAT CONVERTS TO ISLAM ARE INTELIGENT PEOPLE, POLITICIANS, PEOPLE OF SCIENCE, MUSICIANS, WRITTERS, AND ALWAYS THEY DO THAT AT AN MATURE AGE WITH FULL CONVICTION AND WITHOUT BEING FORCED TO CONVERT.
I LEAVE YOU A LINK THAT WILL TAKE YOU TO A SMALL LIST OF FAMOUS PEOPLE THAT CONVERTED TO ISLAM.
