However, I think if someone is being accused of being a predator based on other facts than they are just trans I do not think that in itself is being transphobic. Now say Cherry was just calling her a predator because she was trans and that was the sole reason then I would say it is probably transphobia.
In this case I think there is a reason someone is being called a predator and they just so happen to also be trans. You can be trans and a true predator... it just does not make all trans people as a whole a predator.
