It is the nature of their cult religion of death. People need to read the koran and hadith to find the truth about the 'religion of pieces' and body parts.
Sura (2:191-193) - "And slay them wherever ye find them, and drive them out of the places whence they drove you out, for persecution of Muslims is worse than slaughter of non-believers...and fight them until persecution is no more, and religion is for Allah."
Sura (5:33) - "The punishment of those who wage war against Allah and His messenger and strive to make mischief in the land is only this, that they should be murdered or crucified or their hands and their feet should be cut off on opposite sides or they should be imprisoned; this shall be as a disgrace for them in this world, and in the hereafter they shall have a grievous chastisement"
Sura (8:12) - "I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them"
Bukhari (52:177) - Allah's Apostle said, "The Hour will not be established until you fight with the Jews, and the stone behind which a Jew will be hiding will say. "O Muslim! There is a Jew hiding behind me, so kill him."
Tabari 7:97 The morning after the murder of Ashraf, the Prophet declared,"Kill any Jew who falls under your power."
Ibn Ishaq: 327 - “Allah said, ‘A prophet must slaughter before collecting captives. A slaughtered enemy is driven from the land. Muhammad, you craved the desires of this world, its goods and the ransom captives would bring. But Allah desires killing them to manifest the religion.’”
I find it odd that leftists who denouce Christians for their viewpoint (which they make no effort to force on others) are the first to defend the “rights” of these “people.” Because if the U.S. were to become a Muslim country, leftists would be the first to be put to death.
