Or at least not if we're talking about having public rational discussions about it. The validity and correct interpretation of evidence is extremely hard for a lay audience to judge.
Putting a climate scientist and a climate science denier on a podium to have a rational discussion is not likely to lead the audience to a more rational decision. Ditto for creationists.
Does this concrete case fall into this category? My initial guess would have been no, and that a more rational engagement would have been the better way to go about it.
But after reading parts of the memo, and skimming the rest, I am not sure any more. There is an overwhelming scientific consensus that most of the gender structure we see today is cultural. This is not in contradiction to the existence of innate differences. The problem of the memo isn't that it differs from this consensus, the problem is that it doesn't acknowledge it (and rather treats it as a misguided "extreme and authoritarian" ideology).
I believe there are many things in the academic consensus worth criticising, I also believe that there are many more things in the political consensus built around it to criticise. But that's not really what this memo does.
For example, it selectively cites a tiny corner of the research literature, conveniently ignoring the mountains of evidence that don't fit the stated thesis.
