If you will ask someone of the Islamic faith, they may tell you about the things that the Muslim are doing and that is the bad things. Because peace is wanted and not war so people may naturally dislike the faith and the people. But thankfully as Islam people live with their faith and life without making problems as opposed to what is known so many people now know that not all Muslims are into war. Here is a video about people converting to Islam.
It illustrates the fact why there are many who are converting into the Islamic faith. each of the people who had converted has their own reason to turn into the faith rather than stay on the faith that they were born to. This shows that the religion is also a religion peace. But there is the debate on whether it is good or bad. That is basing on what they could see. But there is the explanation that those who make war on Christians are following the teachings of the prophet.
But it should be understood that there is also the other part that was written by the prophet to doing good and not just killing Christians. The certain rules that were given are fit to the life f people who like the doctrine and so they come to convert to Islam. They are now the ones who are spreading the message of what is truly happening in the faith that is seen negatively by the world.
