Neither do they want the traditional family to exist either, as evident within Marxist ideology.

Since the LGBTIQA+ etc. group consists of a very small population, implementing this form of education would be similar to replacing traditional content of human anatomy to account for all the disabilities that exist. In an education curriculum, it is pointless so therefore we generalise based on what most people are.

Besides, this kind of ideology is definitely not for kids, especially due to their inability to actually critique ideologies as a result from the lack of life experience. Their world is they know it only revolves around themselves. It's only until they become teenagers that they have at least a hint of an idea as to how the world is like. It's only until they leave high school that they are truly exposed to the world.

Another problem I have in teaching these sorts of things is that it is a twist on what we all understand, everyone is unique in their own way. These kinds of doctrines (radical left identity politics), attempt to categorise everyone based on sex, gender, and race. Based on the idea of everyone being unique, it's possible to categorise more people into more categories, such as height, attractiveness, eye colour etc. It is an endless list.

Therefore, why on earth should we make more things complicated to the point where we create a generation of children who have no idea who they are and therefore create a nihilistic society?
