because leftists rely on critical literacy to enforce your worldviews through the use of language and definition restructuring, while also changing fundamental learning concepts (ie. moving from phonics to whole language when learning to read) to help reduce your ability to critically think or otherwise question their idea of the status quo, despite explicitly trying to teach you to be critical of the powers in place that resemble their idea of power disparity
the fact that this approach to think critically about power disparity and bias's in writing and reading simultaneously makes people more malleable and subject to question, will somehow not be used to question the same ones who eroded into power, is lost on them.
