Should elementary students learn about gender identity?

This book is found in ELEMENTARY public school libraries in Texas including in Round Rock ISD, San Antonio ISD, Richardson ISD, Waco ISD, Dallas ISD, Houston ISD, Wylie ISD, El Paso ISD, and Denton ISD. This is according to the schools' online library catalogs, and it may be found in other school districts as well.

Here are some pages from the book.....

Is it true that our gender can change from day to day or year to year or that what you feel your gender is can change?

The Marxists have been going after our kids for a while. They fly books like these under the radar in public schools all over our state; most parents don't know what is in their child's school library. Some are ebooks that the children can download onto their Chromebooks so that their parents never see the title. Some are physical books that can be checked out of the school library. Please see my previous blog for more examples of books that are inappropriate for children and are in our public school libraries.

Should elementary students be learning about this? Why would teachers and librarians teach them about this? What is their agenda?
