You moved the goalpost.  Sure, the claim can be made that the Clinton campaign does not have a "true and serious policy".  But that is subjective. The Trump's said: "There’s no policy on Hillary Clinton’s website pertaining to any of these issues, childcare, eldercare, or maternity leave or paternity leave for that matter” and Clinton “has no child care plan”. That IS a lie. 
If one wants to claim it is not "true and serious" that is understandable. But defines what is "true and serious"?  Just Trump supporters?
You said a true and serious plan would have been the subject of speeches. It was.  "Well, if fighting for women's health care and paid family leave and equal pay is playing the woman card, then deal me in!"  (DNC convention speech) and this:  "During a campaign stop in Columbus, Democrat Hillary Clinton vowed that as president she would fight for ... paid maternity leave."  How many times does she have to mention it to meet your criteria of it being the subject of  speeches?
