I agree, @PegLegAntoine - and I would add that we need to move rapidly towards a society where we don't pigeon-hole people based on their preferences, whether that be their choice of toys, favourite colours, hobby, clothing, career etc etc.
As long as we have things that are labelled 'Boys' stuff' and Girls' stuff', people of one sex who like things labelled for the other sex will feel that they are pigeonholed by their choices, and that society may well be judging them based on that.
A boy who likes pink, skirts, dolls may well fear criticism and teasing for being a boy who likes girl stuff - which will cause anxiety, fear and maybe depression - whereas identifying as trans will allow them to be seen as brave and inspirational, and to enjoy freely their choice of colours/clothing etc, whilst shutting down any negativity with the hammer of the TERF accusation.
If we moved away from the toxic stereotyping of things for men/boys and things for women/girls to a society where we didn't label things or pigeonhole people based on their choice of colour/clothing/hobby/career, I suspect we would have a happier society, and one where most people could be comfortable in their own skin, and didn't feel the need to transition.
