Budd Hopkins passed away a few days ago. He was a first class alien abduction researcher and so for those who feel uncomfortable with first hand testimony you can do no wrong by listening to a man who researched over 700 cases when the video above was filmed. It's authoritive, informative and compelling. I learned a lot of hard facts from this man and I'm glad I rescued this video from Google Videos and transferred it to Youtube so that others can determine for themselves the nature of this problem which humiliates the abductees once and then again as the wider world rejects (can't handle) their often harrowing testimony.
The short story is that genetics are the most prized asset in the universe. I learned that elsewhere but it's a critical way to understand the issue.
