How about the OTHER six million people murdered ny the Nazis? Why aren't they worthy of mention?

We wouldn't want to offend the holocaust-denying neo-Nazis.

What about other mass genocides? Are all genocides being given equal study time? The largest genocides in human history should be given the main focus as well as the tactics used to commit the genocide. The Holocaust is truly horrific in its own particular way, but lose of life that occurs, genocide, should not be ignored because it is somehow less direct or slightly less planned (I don't know if this is even historically accurate to say it was less planned). I just learned about one aspect of the largest human genocide that has ever occurred. It's so truly horrific it's almost impossible to believe it is true. None of this was ever taught in school. Why not? Is it because we ("we" could probably stand to be better defined in this sentence as "some" )have a vested interest in NOT discussing it widely?

To Holocaust deniers, do they also deny the other genocides in human history? It is quite clear genocide is a very real historical occurrence. Where is the disconnect in their minds?

Wow. I guess that's Texas.

The school and the teachers are torn between teaching civil rights in history and parents who'd rather deny it -- especially race and LBGTQ topics.

From the link:

Gina Peddy, the Carroll school district’s executive director of curriculum and instruction, made the comment Friday afternoon during a training session on which books teachers can have in classroom libraries. The training came four days after the Carroll school board, responding to a parent’s complaint, voted to reprimand a fourth grade teacher who had kept an anti-racism book in her classroom.

The debate in Southlake over which books should be allowed in schools is part of a broader national movement led by parents opposed to lessons on racism, history and LGBTQ issues that some conservatives have falsely branded as critical race theory. A group of Southlake parents has been fighting for more than a year to block new diversity and inclusion programs at Carroll, one of the top-ranked school districts in Texas.

Late last year, one of those parents complained when her daughter brought home a copy of “This Book Is Anti-Racist” by Tiffany Jewell from her fourth grade teacher’s class library. The mother also complained about how the teacher responded to her concerns.

Carroll administrators investigated and decided against disciplining the teacher. But last week, on Oct. 4, the Carroll school board voted 3-2 to overturn the district’s decision and formally reprimanded the teacher, setting off unease among Carroll teachers who said they fear the board won’t protect them if a parent complains about a book in their class.
