Do TRAs actively campaign against 'gender reveal' parties etc?

[yetanotherusernameAgain]

Just wondering. Does anyone know if TRAs either campaign or are vocally opposed to the concept of gender reveal announcements, parties etc? I don't mean targeting individuals holding such parties, just a general anti-gender reveal lobby.

Shouldn't they be pointing out the error of 'assigning' gender to a baby before it's even been born? Just wondering if any of them direct their energies to that.

And if gender (sex) reveal parties get cancelled there will be some truly awkward moments after birth when the mother asks her midwife 'is it a girl or a boy?' , and the midwife replies 'I really don't know , we just can't tell these days '.
