There are a few problems that these young people have.
One is they don't have a clear grasp of the biology. Too many people who seem authoritative, like the medical establishment, seem to be onboard. These are the same young people who are hearing that anyone with hesitations about new drugs or vaccinations are "anti-science". They have an implicit trust in certain kinds of authority.
They also have very little in the way of good critical thinking skills. They have been told, however, that they do. What is taught in schools is largely dogma - they are given just the right information to make sure they come to the right conclusions, with an emphasis on being critical of certain things: anything that can be considered colonialism, "conservative" as they've been taught to define it, anything done by Europeans, etc. They have a flat and unsophisticated understanding of power structures.
They are afraid of open argument and would consider something like a serious discussion of the legitimacy of historic slavery to be deeply offensive. They do not know how to construct an argument to support their position.
They do not understand that rights are not only NOT the only way to think about things, they aren't straightforward. That there are often conflicts and needs to balance varying rights in the law or individual circumstances. They aren't taught this.
They believe their sense of self, while on the one hand it is totally personally defined and subjective, requires affirmation from all around. Self-actualisation happens through choices about identity and consumer activity.
They have almost no understanding of historical changes in thought or real understanding of how different cultures think or value things differently. They often think such understanding is inherently "problematic."
Most don't read, or only modern books if they do.
As far as I an see, we have a few generations educated with only the purpose of becoming boosters for certain social justice causes, and so they have to be taken, step by step, and very gently, through the concrete effects of these things they support. Men in women's prisons, for example. Even that is too difficult for some.
