(Note June 7, 2019— I have added more information about extreme passages in the Bible.)
Videos like this one are one of the biggest reasons that people don’t understand the serious threat that is posed by Islam. Islam is in no way similar to Christianity— it is more than only a religion, it is an ideology and a political system which dictates how its followers are required to live all aspects of their lives, and Muslims are expected to take it very seriously. In many Islamic countries, Muslims who leave their religion are actually executed for doing so.
As the above video shows, there are extreme passages in the Old Testament of the Bible such as ones talking about stoning people for blasphemy and adultery, however it does not mention that there are no such passages in the New Testament, and the New Testament certainly takes precedence to Christians. Christ was a pacifist and a healer who came to put an end to suffering, he was not a conquering warlord and an enslaver as Muhammad was.
There are a few examples of Christian terrorism being inspired by the Old Testament, but it is statistically insignificant compared to the massive amounts of Muslim terrorism which occurs based on the instructions of the Quran.
There is a passage in the New Testament which is often misinterpreted as Jesus telling his followers to kill people (Luke 19:27) which reads as follows: “But those mine enemies, which would not that I should reign over them, bring hither, and slay [them] before me.” However, this statement is misinterpreted because it can easily be taken out of context. In fact Jesus spoke those words when he was in the middle of telling a parable— he was telling a story about someone else and not actually giving a command to his followers. See this link for more information about that passage.
See the Open Minded Realism article “A comparison of aspects of Christianity with aspects of Islam” which discusses important differences between the regions in more detail.
