Quite - even when they’re not western they are (Doctor Bashir).
That doesn’t bother me, because it makes sense for a lot of races to self-segregate duty stations based on biology.
Klingons are a bad example, because they’re not part of the Federation, and you’d expect Worf to be nearly unique. But take Vulcans & Humans. Vulcans come from a world that’s mostly desert, and I imagine the they prefer their ambient environment noticeably hotter than Terran; it wouldn’t surprise me if the artificial gravity settiings on their ships are higher than Earth normal, too. Spock may have been willing to put up with a perpetually chilly, oddly light environment during work hours, but I bet it was uncomfortable, and I’ll bet more that the vast, vast majority of humans wouldn’t do the reverse. If the Intrepid’s gravity is set at 1.5 Gs and the average temp at 98 degrees F, most humans are not going to want to serve on it. And certainly Andorians, who like things much colder than humans, aren’t going to serve on the same ships and bases as Vulans if they can avoid it.
Actually, there was at least one episode that shows the concept of “shifts” in action on the bridge. I think it’s the episode about a day in the life of Data (“Data’s Day”(?)).
Gawd,
Jon Lovitz as a Harry Mudd Jr. would be so damn perfect!
Yet another thing to long for but never have fullfilled before I die.
Who would be the perfect cast for Mrs Mudd Jr. I wonder.
Riker: Captain, this guy is over the top!
Picard: Yes Number One. He makes our acting look almost natural by comparison!

When Spock was suffering from premature aging in The Deadly Years, he turned the heat in his quarters up to IIRC, 130° F. I suspect Vulcans and Cardassians are the two most thermophile humanoid species in the Trek galaxy.
And Klingons, but they refuse to admit just how uncomfortable cold makes them. I mean, a four-year-old Klingon girl is gonna be more macho than most Earth men.
These. Star Trek needs more of these.
How about just what’s inside of that? You know, without the irrelevant outer material.
Can someone spare a thought for the gals/gay men who watch this show? It’s not like the Trek franchise doesn’t have enough tits in it already, all we get is Riker (beached whale anyone?) and Bashir (who is so like Gaius Baltar it’s unreal).
You sure that wasn’t a slash/fic plot? 
Yeah, but the way Riker lurches when he walks should give any proper woman the vapors 
Riker is a beached whale? How’s Geordi’s VISOR woring out for you?
Amen! Genie Francis is a lucky woman.
Seriously, most straight women fans I know (can’t speak for gay men) are quite satisfied with the yummy quotient of Picard, Riker, Geordi, Worf, Bashir, Sisko, Chakotay, Paris, Harry, Archer, Kirk, Spock, Scotty, Chekov, and for those who like a touch of the quirky, Data, Odo, Dukat and Garak. Read fanfic if you doubt anyone finds the above characters sexy.
Published novels too, for that matter. Through the fault of one of those (or maybe it was an episode with Vash) and no desire of my own, I have the adjective “virile” inextricably linked with Picard.
ETA: And it isn’t helped by pictures like this.
Of course, Star Trek wasn’t the only series to do this. Firefly was set in a system where everyone spoke Chinese — yet there were never any actual chung gwok yan to be found.
Mercy! That’s … a nice picture. And a funny one.
And your mentioning of Vash reminds me that I inexplicably forgot Q in my list of yummy Trek gents.
The Akagi participated in the blockade along the Klingon/Romulan border.
That wasn’t the Practice! That was L.A. Law!
{kids these days}
nm…mistake already pointed out later.
The Enterprise-D’s sister ship was the Yamato, I remember that much. Personally I never saw the resemblance.
If I recall aright, the ship blew up for some reason, possibly for the glory of the Emperor.
