The Get Down is really giving us bisexual Dizzee. They are truly acknowledging his attraction towards multiple genders. They are identifying him SPECIFICALLY as bisexual.
They’re not using his attraction to men as a stepping stone to being “fully gay”. They’re not treating this as a fling, or as an experiment, or as a phase.
Dizzee Kipling is really, truly, 100% bisexual, confirmed by the showrunners.
