I don't know about this particular instance, but I see the word "complaint" used synonymously with simply pointing out a double standard, as an aside a lot.
As an aside, but not a complaint, here's a double standard that I notice:
It's perfectly acceptable to have a commercial where the man is an idiot (often with money, but it can be with anything -- technology, cooking, managing the kids -- and the woman comes in to save the day from her idiot husband. The same dynamic doesn't work the other way.
No it was a complaint not an aside.
