I wouldn't say transphobic as there was nothing "phobic" against trans.
While it wasn't the best of statements from Anne (and I don't know much about her) - She did use to be a boy (not an opinion), for the sake of the argument she was "on the other side" like women might base their argument on being on the discriminated side.
Was it necessary or meant to support a serious debate about these things? there wasn't much of a thought behind it. People say stuff...
If it's a discussion about gender issues - Anne brings the fact of being herself a woman, like Paris bringing the fact that she's a transwoman to the table (and it's something that India has discussed on CBB21 - changing sides from the "oppressive" gender to the "oppressed" gender, which is a valid point).
