Just in case you don't know, the time travel paradox that I'm talking about is the belief that time travel should never really change anything. The reasoning for this is that if something has been changed in the past, you should be already living in that reality. In the story in The Terminator, Sarah meets Reese, who had traveled back in time to protect her from the T-101. Reese tells Sarah that she will give birth to a hero that will defeat the machines that aim for human extinction. Of course Sarah gets curious of who the dad will be, and Reese tells her that John (her future son) never knew him, that he died before the war. Long story short, Reese and Sarah end up hooking up, but Reese dies as Sarah finally kills the Terminator. This fulfills the timeline Reese told Sarah about, therefore keeping the timeline constant.
Now this is subtle, and there isn't really any cultural issue presented here, but I thought it was pretty interesting. Since the Terminator franchise as a whole takes place in more than a couple different timelines, it's interesting to see that the original creator envisioned the story in one loop.
