A toast to Earthmen, who, despite their faults, have that unique ability to charm women of all races, in all corners of the galaxy.
I take this canon quote to heart, coming from a Federation planet's ambassador, who actually ended up marrying a human, coupled with a lot of examples that support it, like for one, we hardly ever see any mixed breeding with two different alien species. They nearly always are half human hybrids.
One can extrapolate from this, that much like Vulcans have logic, & Klingons have honor, & Ferengi have greed, the most pronounced attribute one might say of Star Trek's humans is that more than any other species in that universe, they seem to possess the greatest amount of... charm. What
they do is talk you to death, until even the most ardent enemies, if they have any sense at all, usually come around. lol
So, who better to utterly pack your starships with, to send out into the vast reaches of the galaxy & make contact/treaties, conduct commerce/negotiations, etc..? You're virtually guaranteeing yourself successful development of your federation.
So there you have it. We're just the friendliest, & most charming, with greater numbers who WANT to be out there more so than others in the UFP. That's my take anyhow.
