I have no idea what numbers you are using for the American population, but your conspiracy theory is absurd.
This would be a massive and complex and many years running conspiracy, and Cosby would simply destroy the women’s credibility and timelines and claimed locations around the nation and claimed list of homes and restaurants and hotels, and public events, and all of his friends and co-workers would be rallying around him telling us how this would be impossible because it doesn’t fit his reputation among them, and Cosby would not have settled out of court in 2006 for drugging and raping a woman when she brought forth 13 more Jane Doe victims.
Not a conspiracy. 7 billion on Earth, dived by two.
You are an idiot.
