An off-the-wall honorable mention here: Star Trek, The Next Generation.
The first couple of seasons were painfully New-Agey (and sometimes just plain painful), but later eps had several outstanding episodes touting conservative themes.
One of my very favorites was the two-parter “Birthright”, in which Worf refuses not only to give up his values and way of life to fit in with the touchy-feely, kumbayah Romulan-Klingon prison camp, but also works to undermine the camp itself.
I’d put Deep Space Nine in there. Sisko was the least PC of any captain other than Kirk. Plus, I might not have been a fan of what Ron Moore did with Battlestar, but he injected capitalism directly into the Star Trek world on DS9. Plus, religion finally got a somewhat fair shake, even if it wasn’t our own (though, Sisko’s father did something shocking on one episode—he quoted the Bible).
