I wouldn't say that, with the exception that I don't know what a primo is so I can't really comment.
Having travelled to every continent on the globe and worked closely with locals on each of them and made friends of varying degrees, I don't find the overall attitude that "people are the same everywhere" to be an entirely accurate statement, either, unless what we're talking about here is a realization of Maslow's hierarchy. As enjoyable and rewarding as it is to build intercultural relations, I think people make a mountain out of a mole-hill when they share a pleasant conversation with someone, exchange a smile, or find some other similarities. I think if a rural American sat down for a conversation with a Pashtun tribesman and was able to put aside their mostly incorrect preconceived notions formed by western media, you'd find some surprisingly interesting cross-overs, but that doesn't mean we're the same.
I just see this "people are the same everywhere" kumbaya boner-fest bullshit as the opposite end of the spectrum of making certain races out to be sub-human, but essentially the same thing. The truth is more in the middle. No, Africans aren't monkeys, the Huns aren't blood thirsty savages with eyes that glow red, and the Japanese and Chinese aren't barely-sentient creatures.....but neither does that mean we're all the same everywhere, and I think you'll find that mindset common among the non-rookie members of international organizations that many of the rural/conservative/libertarian members of this forum who've barely been overseas themselves frequently refer to as lib-tard special snowflakes with their heads in the clouds, etc.
If I'm taking the "we're all the same everywhere" thing out of context or for more than what it's meant to impart, that's possible too.
