“Brad, you have never taken out the trash once in your life,” she replies.

Without reading the context and just looking at that quote... yeah, probably! If he's really never taken the trash out once in his life and they're married, then either they have an arrangement where she's the one taking out the trash, or they'd be totally covered in trash.
... getting in before the "maybe they've only been married a couple of days and this is the first load of trash" - then how does she know he's never taken the trash out in his life?
What if a man comes home, and says to his wife:
“Susan, you didn’t take out the trash!” he says.
“Brad, you have never taken out the trash once in your life,” she replies.
Would it be fair for him to turn, smugly clutching a copy of The Economist, and say, “Susan, this is not about me. I can’t believe you are doing whataboutism”?
