Bean,
As a person who professes to be a Christian, I will agree with you that some of the worst events in our history have happened in the name of religion. But just because someone uses the name of God when he engages in a violent act, doesn't make that act the will of God, nor does it make the act a true representation of the religion. Just listen to all of the Muslims today telling us that the Koran doesn't teach that people should fly into buildings. The fact that a nut thinks that it does is not an indictment of the religion, but of that person.
Chrisitanity doesn't teach bigotry, racism, or to be hypocritical, yet people who profess to be Christian sometimes are. Does that mean that Christianty is wrong or the person? Roman Catholic priests who prey on children are sick people who should not be representing the church, but what condems the church is its response, not the actions of a few.
The message of Jesus was clear. Love each other as Christ loved us. Forgive each other and you will be forgiven. It is very simple.
The debate about the Trinity, etc.. does not make that message any less clear. Within the realm of orthodox Christianity there is room for differing opinions about details that do not destory the ultimate message. The JWs are not what I would consider to be orthodox christianity so their differences are outside that realm.
The miracles that Jesus performed when he was walking the earth were not just for those who witnessed them. They were preserved for the ages. We know about them becuase they were.
As for the Bible not being trustworthy, I would suggest that you study the history of the Canonization process and the evidence of the sources we have to make valid translations. Of all of the ancient texts, the Bible is the most documented book in history. For example, ther are over five thousand New Testmanet Creek manuscripts, compared to only 650 of the Illiad. These New Testmant transcripts are as old as 150 A.D. As for the illiad, the earlist manuscript is over 1000 years after it was originally written. With that many copies of the New Testment writings preserved today, ther is no way that the RCC could have changed the writings to fit their needs ( As the JW did). We would know the difference and it wouoldn't have stood the test of time. As for the old testament, simply refer to the Dead Sea Scrolls where there are almost complete books of every book in the Old Testament. Only discoverd in the forties, the RCC could not have had any influence over these writings.
God Bless you in your search.
