Impressive answer and so quick! I can never think of good comebacks until hours later if at all!
I suspect that given that Lowri is frequently on this show and knows that JV (and therefore accolyte Storm) are firmly part of the BBC inspired trans rights are always rights, that she is well practised in putting forward the women's rights position.
It's a shame the host spoke over him and didn't allow him to respond, which clearly puzzled him.
JV doesn't want any open discussion about trans rights. The stand in presenter will have been well briefed to stir away from the topic.
.
Its worth remembering the JV got this slot because the previous presenter wouldn't apologise on behalf of a guest who pointed out that a trans woman is born male. And was forced out.
And this from a programme made by the news service ITN - speaks volumes.
So JV got an extra show that he certainly doesn't need the income from as one of BBC's highest paid employees, by back stabbing a colleague because he is happy to be a trans cheer leader.
