Putting aside the absurd notion that you can convert a person’s inner beliefs by force, Islam furthers group think by the concept of the Umma, the Borg-like idea that once you are part of Islam, you cannot leave, no matter what else you might come to believe as being true. No “Religion of Peace” is very peaceful if it teaches that its members have a duty to kill anyone who disagrees with it.
Thus, people who practice Islam must be very conflicted in side, especially given that the Koran states Allah can change His mind at any time. While the God of the Bible says that He does not change and that no one jot or tittle of the Law will be done away, Allah says he can “abrogate” anything he dictated in Mecca and replace it with anything he likes at Medina. see 2:106

This may be a good time to bring up AGAIN why Obama is dangerous as long as the public remains ignorant of the truth about Islam. He was born a Muslim, to a radical Muslim father. There is no way that either he or his mother can be considered other than Muslim by Muslims. The fact that they're still alive shows complicity, IMO.
