@Vette888,
The premise seems to be based on the idea that alien civilizations will exhibit the characteristics of human society – paranoia, fear of the "other", and the universality of predatory behavior.
It posits the likelihood of advanced alien civilizations and then uses the total lack of evidence for their existence as evidence itself since these civilizations obviously wish not to be discovered.
Another plausible explanation for the silence of the universe is that alien civilizations, if they exist, may have developed communication technologies which aren't based on the broadcast of electromagnetic signals. Or that advanced forms of extraterrestrials exist successfully without establishing civilizations.
