I don't think they do find it in the slightest bit controversial. It's only because there is an ideology that is being challenged, making it difficult to articulate.
We have somehow come to the conclusion that to oppose this ideology sounds intolerant, illiberal, mean, wrong, unfair.
Many people are under the impression that trans people as a cohort are an oppressed minority. Wanting to just get on and have a semblance of a life without abuse and victimisation.
Stephen Whittle, from Press for Change speaks about this all the time. In fact Whittle is on the same programme as Kathleen Stock - Gender Wars, describing exactly that.
But of course, the reality, and indeed stonewall's definition is that the cohort is also made up of cross dressers, drag queens and transvestites. We know from trans widows that self confessed fetishists are also part of the cohort. And from sports that male individuals claiming to be women are also part of it. Not to mention rapists and sexist offenders.
Many who make up the cohort are far from oppressed and marginalised. Quite the opposite.
No one in their right mind would view a rapist being given access to incarcerated women as the victim in the equation.
And you can see the reality butting up against people when they speak.
On the one hand they've been told that the entire cohort is an oppressed, victimised minority. And on the other hand, they see the reality with their own eyes.
