Islam was not hijacked as you state. If you read the Quran and the Hadiths, you will realize that it teaches that Islam is the only truth and that it must be spread by force if necessary. There are a number of passages in the quran that teaches intolerance, bigotry and hatred. You should stdy the many archives in faithfreedomdotorg to know the truth.
That having said, it does not mean all muslim people are bad.
