it’s pretty bad, friend. here’s why:

• super cissexist/transbigoted in general.
• erasure of trans women and trans men via equating breasts & vaginas to women and flat chests & penises to men, ignoring the fact that trans people, both binary and nonbinary, exist and are not defined by their genitalia. 
• erasure of intersex people, as well.
• nonbinary erasure (due to the fact that “genderbending” in and of itself  treats male and female as if they are the only two genders and that they are the “opposite genders” from one another, despite the fact that gender is a spectrum and therefore there’s really no “opposite” to any gender).
• generally presents as a toxic ideology that when one’s genitalia changes, so does one’s entire gender identity, completely disregarding the individual’s original identity for the sake of equating genitalia to gender.

things to consider as an alternative to “genderbending”:

• trans interpretations
• trans interpretations
• trans!!! interpretations!!!
