"They try to "solve" the differences between the two religions in 3 minutes, good stuff"
There is no way to "solve" the differences between these two religions. The differences are fundemental to the beliefs of each. Christians believe that redemption is through the sacrifice, and shed blood of Jesus Christ. Followers of Islam believe redemption is through belief in Alla, and his prophet Mohammed, and that their good deeds must out weigh the bad. The only similarity really is FAITH.
As to who is right or who is wrong, well, one day we will ALL find out.
Oh, and yes I am a Christian.
