It's a bit funny how someone mentions something and then Snake goes "The Patriots??" and I have no clue what the fuck is going on and then there's this la li lu le lo shit or whatever and FUCK YOU MGS.
To clear this up for you, The Patriots control the flow of information (still) which was the whole point by MGS2. Because they're a secret organization, NO ONE knows they exist except for a select few. Raiden, Snake, Otacon, Ocelot etc. can say their name but whenever it's mentioned to someone outside the inner circle it immediately becomes La Li Lu Le Lo.
Imagine speaking a foreign language to someone. You know what you're saying but they have no idea and it comes out as gibberish instead. Whenever someone mentions the patriots, it literally becomes gibberish. It was kind of a "Holy crap, that's a really well executed thing" in MGS2 and I smiled a bit when it when Meryl's like "WTF R U TALKING 'BOUT SNAKE?"
