I mean, I think that's why I got confused because in your post it says that she was strictly anti-meta until she became one. But you're saying that she's now anti-Cape. I thought they were the same things.A Meta doesn't have to be a Cape. A Meta could be a villain or just your average citizen living a normal life. Batman was a Cape but he was never Meta. Green Arrow was/is but he was never Meta. Not all Metas are Capes and not all Capes are Metas.
TL;DR: Cape /= Meta.
If this is how she thinks, doesn't that imply that she won't get along with anyone at school?She's not there to get along. She's there to learn so she can stick it to some asshole newspaper owner. But she will be play nicer with the Cape wannabes than an Amazonian. Cape wannabes can be taught better, Amazonians by the time they leave the island are already brainwashed beyond hope.
