The thing to remember about Rebecca, is she has been a disingenuous feminist first, and a skeptic second, since day one.
She started with the Skepchick.org blog and messageboard, which basically allowed her free reign to express skepticism or radical feminism interchangeably. Inviting her to join the SGU podcast just increased her exposure, and artificially tempered most of her exposure since Steve Novella runs the show and she couldn't use it as a forum to pretend feminist dogma was actually "science".
But keeping her corralled into actual science discussions on the podcast didn't stop her from using that "celebrity" to push her real agenda.
Keep in mind this is a woman who:
produced and sold nude female calendars (with unpaid models), but also claims women are exploited by anyone else doing the same thing
turned a conversation in an elevator into a veiled rape threat
refused to attend TAM events after telling a gay man he didn't understand harassment, and he refused to let her draft "ban anyone I dont' like" policies.
tricked an entire conference into attending her wedding, instead of the skeptic talk they paid for
moved to London and since the SGU was now recording in the middle of the night for her, participated by whispering so as not to wake up her husband.
missed a significant percentage of podcast recordings because it was literally her lowest priority
cut all ties with Richard Dawkins because he had the nerve to say she was over reacting to the elevator incident
Rebecca is not a scientist, has no education or experience in science, and has only the vaguest idea of what skepticism is and only as far as she can use it to advance a feminist agenda. So it's not very surprising she's giving talks on subjects of science that she has little to no understanding of.
