Transgenderism is not content with merely abolishing the distinction between man and woman. It also aims to discredit any form of thinking that involves drawing binary distinctions between things.

Few have realised how dangerous this is. The act of drawing binary distinctions, of discriminating between different categories of phenomena, is central to moral thought and the formation of moral judgements. It allows us to distinguish between good and evil or right and wrong. Therefore the attempt to devalue the drawing of binary distinctions is not only an attack on reason, it is also an attack on our ability to exercise moral judgement.

This challenge to thinking in distinct, binary categories has, of course, been particularly aggressive in relation to identity and gender. Advocates of transgenderism claim that binary gender and identity categories violate and harm those who do not identify themselves in binary terms.

Moreover, the attack on binary categories often calls into question normality itself. ‘In modern society, there is a huge misconception as to what is normal and abnormal’, writes one blogger. ‘The fact that there are two such categories, normal and abnormal, is just a reaffirmation of this misconception.’ One psychotherapist even challenges the validity of using normal and abnormal to refer to people’s mental and emotional states. ‘It is a real question as to whether those words can be sensibly used at all’, he writes, ‘given their tremendous baggage and built-in biases and the general confusion they create’.
