Here is the University of Chicago newsletter about how Nussbaum is using the prize money to support student roundtable discussions about "issues that can be challenging and often polarizing". The relevant paragraph from the story is:

Nussbaum has led two roundtables since the program began: one on #MeToo with Prof. Adam Chilton, and one entitled “Whose Wedding Cake?: Antidiscrimination and Religious Exemptions” with Prof. William Baude. She and Baude are currently planning their next one, a discussion of transgender bathroom issues scheduled for April.

Some context on "transgender bathroom issues" in the US, for those who happen to not be in the know:

The GOP has used LGBT issues as a wedge to try to drum up support from their base. This goes at least as far back as the 90s, with shit like the "Defense of Marriage Act". Another prominent example is the Bush campaign making same-sex marriage a big issue of the 2004 presidential campaign. But Americans as a whole became more supporting of lesbian and gay rights. E.g. since 2011 more Americans have supported same-sex marriage rights than opposed it [link]. Since homophobia is no longer so popular, Republicans have had to pivot to a new variety of scaremongering.

Enter the so-called trans bathroom bills. In short, these bills legislate that people must use restrooms corresponding to their """biological gender""". Perhaps the best known of these is North Carolina's HB2. (HB2 had other awful provisions. It was later partially overturned, with some of the odious shit in it remaining on the books.)

There is no rational reason to support these laws. The only basis for them is hate.

Tobias Barrington Wolff, part of the law faculty at University of Pennsylvania has a nice breakdown of what he calls the ugly fantasy at the heart of anti-trans bathroom bills. His essay is good, and you should check it out. But let me summarize the point.

Everybody poops and pees. That includes trans people. Participating in the public sphere, using government buildings, going to schools, working at an office, etc., requires access to a place to poop and pee. Hence why such spaces are required to have restrooms, since humans can't indefinitely store poop and pee to dispose of in the privacy of their own home.

These bathroom bills forbid trans people from using the restroom corresponding to their gender. But nor can they use the restroom for the other gender. Someone who looks like this isn't going to be welcome in a men's restroom—especially in an environment where vigilantes are encouraged to police who uses what restroom—for the same reason that no woman is going to be welcome in a men's restroom. (Cf. the quoted email from the section for Hawaiʻi in the link two paragraphs down.)

So these bathroom bills are an attempt to expel trans people from the public sphere, to legislate them into nonexistence.

Of course, backers of these bills don't come out and say this. You don't wanna say the quiet part loud. It makes it too obvious what's going on. So instead they trot out complaints about the danger of harassment, protecting women, protecting children, etc. But these are lies. Lies which have been debunked for years.

So there is no rational basis to give a platform for someone to argue for anti-trans bathroom bills. It is giving a platform to hate and lies, without any redeeming features.

Now, this is not to say that these roundtable discussions are all bad. (I personally question the value to society of students at an 'elite' private school having roundtable discussions about "issues that can be challenging and often polarizing", but that's neither here nor there.) But the upcoming April roundtable is a mistake.
