Godseeker30 here. Regarding your questions about religion and God, personally, I don't believe that those in the crusades, who were killing others in the name of God were doing it for God but because they were mislead. That is my personal opinion. Regarding other questions you had about is religion or faith very real, it is, just read some of the parables in the Bible if ya have a chance, if you're not sure if it's real or not. The bible is man written, but God had inspired these people to write, what He wanted them to write, so if God did, then He musta had a reason right???
