“I grew up with Harry Potter and loved it and I’m interested to see the new [whatever]” is not equivalent to promoting transphobia.
It is equivalent, because in this case, it is literally promoting transphobia. One of the worlds leading transphobes will directly benefit from the profits this show makes, and will directly turn those profits against dismantling the rights of trans folk.
This isn’t an analogy, it’s not dramatic license, or over exaggeration.
You cannot make a black and white determination like that without context and intent.
If you know she will hurt trans people with the money she makes, and you do things that continue to make her money (which includes just advocating for continued consumption of her work), it is black and white, and the context and intent are quite visible.
By itself, it doesn’t mean someone is transphobic. But it does mean that at the very least, personal nostalgia is more important to that person than the harm their actions cause. And that is plenty of intent and context.
As I said, if not voluntarily giving money or making excuses for someone who will use that money to hurt people is too much to ask of someone, then their context and intent is quite clear.
Including yours.
