“Do you agree, or do you think a logline without an explicitly stated inciting incident is a no no.”

Personally I don’t think a logline absolutely needs an inciting incident. There’s actually a thread DPG started where we discussed it in detail.
To me, the most important parts are: 1) Hook 2)Characters 3)Plot/goal 4)Inciting incident.
As long as you have the hook, dangling out there in the logline, and it is concisely written and conveys some sense of the plot, it is debatable whether an inciting incident is necessary.
As for??After he starts hearing what women think a chauvinist ad exec gets the chance to steal back his job from a female rival??it’s a bit different because it does imply the inciting incident. But it puts the hook front and center, and it actually offers a clear reason, due to his chauvinistic nature: How could a mere woman deserve the job more than him?

I hope this helps.
