DS9 made observations about humanity that contradict Roddenberrian wisdom and that weren't taken seriously until 2001. It was an 00s show that aired in the 90s.
I thought I was the only that felt this way! I think DS9 was ahead of its time in many ways. I mean may of the topics the show dealt with like war, terrorism and religion became major issues after 9/11.
DS9 didn't get the respect is was owed when it was on the air.
