People who talk like that have only seen pictures from the show, or they watched it a little bit when they were a child and don’t remember 99%.
Because Xena and Gabrielle did pretty much everything except the physical deeds. And it was recently confirmed in a comic, where they kiss and say they love eachother.
Hell, you could probably show them the old show with the parts set in modern times and they’d blow their gasket. Becase the reincarnations are the opposite genders for a while.

Although it has to be said: It was technically a spinoff from Hercules, and there are crossover episodes. But that show is not nearly as good, for a multitude of reasons. And it got to the point where Kevin Sorbo(Hercules) is still salty about how a lot of the crew went over to Xena. He has even accused Lucy Lawless on social media of “stealing” crew from his show. To which she just laughs and mocks him, like she regularly does when he says stupid things.
