I think she's right that there is a pattern of slash fans rejecting canon het pairings that involve one of the halves of their OTP. I just don't think that that is by itself evidence of misogyny, particularly as there is plenty of evidence of slashers accepting or even supporting other het pairings.
It can be done in a misogynistic way, definitely, but the basic fact that fans of one pairing usually don't want another to become canon, don't want it to eat into the screen time between their favourites, don't want to have to write around it - that's got nothing to do with whether the given pairings are slash or het, in my experience.
