I agree with this post. There are many sources of excellent, factual information about Masonry. There are many books and internet sites, with the most horrible drivel and slander you can imagine. If you wish to get the truth, I encourage you to contact the Grand lodge in your state of residence. Ask them, how to learn about Masonry. They will steer you to some excellent sources. You can also ask the lodge in your city of residence.
One of the finest sites is http://www.masonicinfo.com It is a huge site, with much information, it will take you some time, to go through it.
One individual, was in a situation similar to yours. He wanted to learn all there was to know about Masonry, and write a book about what he discovered. He researched Masonry, and was so impressed with what he found, that he decided to petition Freemasonry, and join the Craft.
His name was John Robinson, and the book he wrote was “A Pilgrim’s Path”. You can get it on http://www.amazon.com
I wish you well in your search for truth.
