Atheists in Science Fiction Television

Despite the religious right's claims to the contrary, explicitly atheist characters are a rarity in television science fiction. Gaius Baltar starts off an unbeliever, but then seems to have religious visions. Adama, as well, in the reboot, has some atheist sounding ideals, but does not make atheism part of his daily life or experience. The only character I can recall from tv sci-fi that was explicitly stated to be an atheist was Michael Garibaldi from Babylon 5. JMS did a great job in making Garibaldi a 3 dimensional character, whose atheism was only a part of his character and did not define him in the way that religion defines the purveyors of the religious right. Garibaldi's occasional statements about atheism often provided some of the best lines of the show, and B5 was fully capable of showing both the best and worst aspects of Garibaldi's skeptical nature.
All this being said, there are a number of shows that do have a skeptical view of the universe that is in keeping with atheist thought. TOS and STNG often portrayed Kirk and Picard destroying alien gods, often computers or advanced beings. Generally, at least until Ds9, the metaphysical explanation in Star Trek was always the wrong one. But perhaps the most proudly skeptical series, and justly so, was Blake's 7. Blake's 7 (as well as its successor Firefly) always assumed the worst of people. The crew of the Liberator did not even care about metaphysical issues. According to the series, all the churches had been destroyed centuries ago. The one episode about religion in B7, "Cyngnus Alpha", portrayed a cultic leader who controlled the people of his religion using a fake medicine. One of the reasons I love B7 is its the only series I know of where the characters sincerely consider becoming drug pushers in order to support their cause!
I think science fiction needs to open up the portrayal of atheist characters. Some series have pointed in that direction, particularly Andromeda's fascinating portrayal of the Nietzscheans in their first few seasons. Atheists, like LGBT characters, need 3 dimensional portrayals. Garibaldi is a start, but I hope to see more such portrayals. At the same time, sci-fi really needs to open up to non-Western religions as well, particularly Hinduism and Buddhism. More complex portrayals of Muslim characters would also be a bonus, as of now there are literally none, a very unrealistic viewpoint.
