This is such bullshit!
First of all you give us some very crappy exampels of people who converted to islam, they are all with african origins, offcourse(well not offcourse, but its very likely) they will want some day to get get back in touch with their roots.
Secondly, why the f*ck do you think that we care that some people converted to islam?! do you think that in our mind we say "So many important people converted to islam, well if it`s so then give me a sec to ditch all my faiths and convert to islam cos a bunch of jackasses that some guy on a
scientific forum shown me ACTUALLY converted to islam, wow!"
Man... you are trying to sell here here a religion that has been going on for
thousands of years, many many
many people died for it and because of it like its frickin` tapperware! jeez!
Note that I dont hate any islamic people, but currently worldwidely there are many major groups of jackass islamic people going from buss to buss exploding to pieces cos of some stupid belief of theirs that ALL who are not islamic must die.
I`m sorry my friend but thats not what religion is about.
I sincerely sugges that you go back and re-read(or read for the first time...?

) the koran and learn its main principals. Then you may continue if you want your preaching around here(which i hardly resent) and people will continue telling you how wrong you are...
Peaple nowadays are not so stupid, you can live with it or continue stumbling... its all up to you.
