Parents are free to defend their so called culture and personal beliefes and read books by Indigineous and LGBTQ7XXTYZ  writes, ON THEIR OWN TIME.

Stop trying to drag the rest of the students down and dumbing them down, and wasting their time of this drivel.  if it's important to the student, they are free to read whatever they want in their spare time, it's these activist groups, many of whom don't have any kids in school trying to line their own pockets, that's what it boils down to.

If you want to learn German, or Chinese  or any other cultural elective, the respective communities offer that separately, they don't try and ram this junk science down the student's throat in order to disadvantage them all.
