Everything you need to know is in the above link. If you labor under any delusion that the CIA has ceased influencing or attempting to influence public opinion, you’d have to be a pretty gullible individual.
The challenge anymore is to suss out who is trying to influence what. Who has something to gain from a particular position or idea? What blows my mind is that there are people out there who consider LGBT activism a “corporate agenda”. It’s incredibly naive to discount the fact that gay people aren’t gay by choice. It’s even more naive to assume that there aren’t young gay couples out there with dual incomes and no children who might want to donate to social causes that aim to make life safer or more comfortable for them. It may be an agenda, but it isn’t corporate, it’s human. What’s more, if you’ve spent any time watching the movement closely you’ll notice that they’re not afraid to include and help other oppressed minorities that they can reasonably scoop up along the way.
