Good question
>"How is a group of humans - no matter how much political power they may have in this society - able to suppress......[pick one]??
Your question is valid, even to me. I have inklings that not all is right in Wunderland.
A lot of things have been ...and will continue to BE covered up.
Catholic Church molestations, the Kennedy assassination, Hitler's internment camps, 9/11, CIA international drug smuggling, the lists are endless. Look at how much POWER the Vatican has. It's political, not religious but hides under the guise of religion.
How about going back to the days of Kepler and Gallileo?
It is PRECISELY the political power all these have had. Who benefited from the fight and profitablity to keep it hidden in the first place?
