Having read a lot of posters here and on TwiX predicting that Trump would do nothing to help against genderism (I remember during the US election, Julie Bindel was convinced Trump would be of no use to the fight), I'm happy to see this EO being put into action, as promised.
I think this promptness, as well as the wording, shows that the Trump campaign realised that their campaigning on the issue of genderism was a definite vote winner and that their voters want to see action taken.
As said above, now we wait to see if Nancy Mace can garner support for legislation to undo genderist changes to women's and gay rights, as well as to protect children from a medical industry that has lost the run of itself.
