It would be interesting if it was forged but it so obviously isn't, that would be a criminal matter as are Mall-rat Roy stripping a 14-year-old to her bra and panties and touching her, trying to force a 16-year-old to suck him off, and providing alcohol to an 18-year-old. Just what Moore has admitted to is enough to never vote for him, if you are a decent moral person that is.
the signature "roy moore, da" was a copy of a signature signed by Moore's assistant whose initials were d.a. when she signed documents for him she added her initials to show that she, not he, had signed it. Whoever forged the yearbook copied that signature without realizing it was not Moore's. The rest of your post is hearsay or unproven allegations.
if proven true, moore should never hold office, but until then, he is presumed innocent.
provide the proof.
