Yes the report, radio programme and presenter were massively transphobic.
Because what transphobic means, the vast majority of the time, is to focus on girls and women. Women's rights are transphobic, feminism is transphobic, women's bodies are transphobic, the very existence of girls and women is transphobic.
In the world according to trans, science, material reality and biology are transphobic. Safeguarding is transphobic. Homosexuality is transphobic. Transsexualism is transphobic. Reality is transphobic.
The only things which are seemingly not transphobic are po-mo, Queer Theory and an industrial medical complex which experiments on humans and makes money from those experiments (and which causes significantly more harm to women and children than it does to men).
In the world according to feminism, things look a little different. Transgender ideology (which is a branch of genderism) is transphobic. Because it declares that TWAW. Almost as though there is something inadequate or wrong with being a transwoman. And if that isn't transphobic I don't know what is.
And transgender ideology is also transphobic because it is a con. It is a house of cards. One big collection of contradictions, fictions and untruths. It has no substance. It is only a thought - a thought that one must try to hold onto in one's head in spite of its utter vacuity. A thought which others must hold in the heads lest the whole edifice disappears in a puff of smoke.
And we all know it. Which is why the OP says that they "know they are a woman" rather than saying "I am female".
It's all just smoke and mirrors. Much harm will be done by such an ideology but it will not endure.
