instead of ‘genderbending’, try trans headcanons instead. try drawing them as a different gender that doesn’t hold up to the cissexist ‘genderbending’ ideas. Instead of swapping cis girl for cis boy, and the reverse, try going from cis girl to trans boy, or cis boy to trans girl, or draw the character as a demiboy, non-binary, genderfluid, anything! there are far more fun ways to explore a character’s gender than swapping cis for cis.
I don’t know about anyone else, but I’ve always assumed “genderbending” to include making a character trans as well as making a character the other cis gender. I’ve taken male characters and made them cis!female, trans!female, and also trans!male, because they’re all interesting and different ways to draw or write the characters. I guess I just view it as “anything but the gender (cis!male, cis!female, whatever) that they were originally”…? (At least for the purpose of art, it matters whether someone is trans or cis to start with, regardless of if they ID as male or female - different jawline, scars, etc. Headcanons, too - it changes how you regard yourself or what sort of life experiences you’ve had.) Sort of how “bisexual” includes “your own gender and not your own gender” and incorporates trans identies in that…?
