When people are deeply soaked in an ideology, and no doubt have lots of strong personal feelings, it can make it very hard to not respond in a knee jerk manner and to 'other' those with different views.
I've seen that a bit in circles i'm in. Because my daughter is autistic and there seems to be a link between autism and being trans identifying I come across parents of trans identifying children more often, I expect, than most.
It does seem that they don't want to engage in any critical thinking about this because they see their job as parent to be to protect their child at any cost and no matter that it affects women's rights or other children. That doesn't matter, what matters is their trans child.
This does also seem to be common with parents of adult trans identifying people, I think we also saw it this week with Jamie Lee Curtis.
What is shocking here is that this politician is making an overt political point which is pretty antidemocratic when the aim is to shut women up.
