Not exactly a selfie but…
The issue I heard raised most about Constantine being portrayed as bisexual is that it’s not his sexuality that defines him.
He’s not defined by his sexuality. But his sexuality is a part of him.
I do not see myself in his occult adventures. I don’t share any features with him. But I am bisexual, and having characters taken from me because it shouldn’t matter hurts.
No, it shouldn’t matter. So why should it matter to anyone that he is a bisexual protagonist?
