Well to lets down to the knitty gitty of the religions that you have listed lets remember the one thing that all of them have in common. Love and devotion to God. I never believe that differnt religions are wrong in fact they are all put together by great devotees of God. At the times in history they spoke to the people of differnt orgins and explained God to them in a way that they can understand. For instance Mohammed spoke to the people during a time of war so his message was very strong and basically gave them permission to kill the invaders of thier land. All religion is a little different but if one is worshipping the supreme being of the universe and loving and serving him how can that be a wrong religion. The subject of right and wrong religion has always been politcal it is the powers that be that make are laws. And it is what they believe that has divided religion through history. The crusades for instance, the rulers of England wanted to purge the middle east and bring Christianty to there. Jesus was killed because the powers that be, didn't belive his message. The healers of the old world were burned at the stake and hung because the rulers didn't understand simple things like putting molded bread on an infected wound, when in fact it was a antibiotic. So my final statement is don't be concerned with who is right and who is wrong try to first understand what is the relationship with God in the differnt religions that you come across then try to understand your relationship with God. If you are truely loyal and serve God with all your heart he will help you find your way to him.
