Yes, faith is free for everyone and we can't force down the throat of anyone to belief. I am born in a Muslim family. However, my family isn't as pious or as strictly religious as those who are scholars or grow up in a total religious school. But socializing within the religious field, I've not seen Muslims evangelism going openly to others to ask them accept Muhammed, although he isn't seen as messiah for the Muslim. How people came into Islam mostly due to observing their kind gestures, morale and good habits of people or good etiquetas. No human wants theory only but the evidence in the act towards one another. I choose to believe that even if the population grows in the world, the Muslims must remember that they must protect the Christians too, allowing freedom of worship. Just like the times of Caliphate Sayyidina Umar Al Khattab.
