I have NEVER known any Mason, who wasn't a good man. My grandfather was one of THE best ! He loved and campaigned / worked to get Teddy Roosevelt elected and told me all about him, when was a little girl. It was so much better and much more informative, than anything I ever got in school, about him.
Please don't hold this against Masonry, just take it as what it sounds like it was; some rather pecular men, doing that which is NOT part of Masonry at all.
