It's probably an awkward way of saying the HP saga wouldn't have happened if no one lived in a closet. Either way I'd like proof this is real—none of the people I saw rightly call out her transphobia are reacting to this.Harry wouldn't have become who he was if he didn't' live in a closet?
That's really the only possible thing I can think of. And saying that Harry HAD to be abused is still a really fucked up thing to say if that's what she was going for.
