One of the weirdest misconceptions about bisexuality is that you can’t have a preference when you’re bisexual. You absolutely can.
I remember when Sara Lance said she preferred women, a very large number of people suddenly started to doubt her bisexuality. The show has always reflected that she has a preference for women, but she is definitely bisexual.
Toni Topaz is bisexual with a preference for women, her preference doesn’t change anything.
