can you please help me with this phrase? I've been digging through the internet for 1 hour and I'm still not able to make an conclusion of what does it mean....

Here are the examples which I found:

1) All these people listened to NPR, watched CNN and MSNBC, CBS, ABC, and NBC and SNL and once they kept hearing from Daily Show and Colbert too that Obama was the better man, how Republicans were bad, Obama good, and that same hippie-dippy-crap about “change, peace, love, unity” they voted for it and bought the farm for this country.

2) All politics aside (and I really mean that — this has nothing to do with his position on anything in particular), I can’t imagine letting this guy loose on the world for four (or, God help us, eight) years. Bush is what he is — and thankfully, he won’t be it at us much longer. But McCain is simply a deeply mean person. He’d be mean to Congress. He’d be mean to the UN. He’d be mean at a barbecue. He’d be mean at the Easter Egg roll. He’s just a jerk, and can only hide that for so long before he blows it. And at risk of sounding too hippie-dippy, I must admit that I think there’s a level of meanness beyond which you are not ideal for the presidency.

3)  A Shah of Iran-type situation could result if we enrage the Pakistani populace as y’ all know, the Prime Directive of Star Trek is non-interference in the internal affairs of an alien civilization. But America’s foreign policy apparatus, whether military or diplomatic, never bought into that hippie-dippy Roddenberry crap. The Prime Directive of our realpolitik is simple.

many thanks in advance guys,

I know who the hippies were, but the problem was that I just didn't know what the word "dippy" means there. But it's clear to me now after your explanation.

thanks again for very clear and good answers.

Best Regards
