i'd say it's a completely fair and true analysis.... and everyone who refuses it is actualy in denial.. as the video states, our species of monkey likes to show and prove how it's diffrent...
and personally, the point of "they think they're supposed to be happy" is probably the strongest point of the entire video... o.0 honestly... we are the only species (well to our knowledge, there's no way to have intelligent communication with other animals, but i still doubt it's wrong) that can't just be... most everything is based around our happiness... actually if you think about it... most everything that's fucked up in the world, could be directly related to our need for being happy...
wanna test it? name something we desire/want/fight to obtain and i'll show you how it can be directly related to our need to be happy... and i don't mean some off the wall obscure shit lol.... you can find a link to from anything to anything if you try hard enough, but those tend to get really obscure and weird... i mean actualy strong links...
as an example (since this is here) we fear death (for the most part) we fear once we're gone we're gone, so we invent religion/afterlife theories, so that we can cope with being gone... and even more so (and more importantly to my point) so we can find a way to cope with losing loved ones.... since death of loved ones usually causes the exact opposite of happiness, there you go... we can forever live in the 'knowledge' that our loved ones haven't disappeared from existance, they've simply entered a new realm...
