Because the charge that this is indoctrinating young children to be anti-conservative would be valid. This isn't a free speech issue, it's a question of appropriateness. Having a graph showing about oranges vs lemons is appropriate for a math textbook. Making an comment about how conservatives are more racist than liberals is not appropriate for a math textbook.
How would you feel if that graph instead showed "56% of all crimes are committed by African Americans"? That statistic is true, but is that appropriate for a math textbook without a deeper conversation about underlying causes?

Is a hard truth indoctrination?

Excellent point. Doesn't this apply to the so-called censorship on Twitter as well? No one is getting arrested, and thus is cannot be a free speech issue. Should Twitter not get to decide what is appropriate on their platform?

What if the purpose of math textbooks should be to teach how math is applied in the real world? A graph of oranges vs lemons isn't going to be good at that.
This sounds like the same argument used to justify "shielding" kids from homosexuality.

This is a great rebuttal. Alone, I would agree it's not appropriate. But if the textbook then proceeded to use math to show why that might be the case, then I would fully support it. In fact, that would be an excellent addition to a statistics lesson for kids.
