To each their own, but I think removing the differing life spans makes the races more flat and indistinct.
Personally I think they’re twice as flat and indistinct when they all live to be 450 years at minimum. From Half-elves to Dwarves to fucking fish people, everything seems to live ten times as long as humans do in fantasy. I agree differing lifespans is interesting, but humans shouldn’t be dying at less than a quarter of the lifespan of everything else.
Technically for the story in that skit, though, the race of the other party was relevant. The mention of “you know how I like a little asian” provides relevancy to the fact that they’re asian(and probably also to the other man being black), because it’s a story about a sexual encounter with them. Nothing wrong with having a type.
