>I can't fathom a math textbook with pornographic examples. Is this a thing in the US?
I've been out of school for quite a while, but AFAIK while there is plenty of porn out there, it's not in our math books.
No, it's just Florida politicos pandering to their base[0].
I'm guessing that what GP is going on about (please do correct me if I'm wrong) is probably some word problems that include references to non-heterosexual/non-binary folks, which seems to trigger the intolerant among us.
Which is a result of decades of attempts to put christian dogma and ideology back into US public schools, and failing that, destroy the public school system.
according to an article linked elsewhere (https://www.baynews9.com/fl/tampa/news/2022/05/06/florida-ba...) it was because they had too many black people depicted as athletes and they had word problems that treated scientific facts as if they were scientific facts.
The one example that I thought might have been somewhat improper was "Multiple exercises related to a debate between Al Gore and Rush Limbaugh, where the publisher was in favor of Al Gore's arguments based on the questions in the exercises."
If the debate in question was fictional, I'd be tempted to agree it would have been better to avoid using the names of real people although I'd disagree that is enough to ban the use of the textbooks. If the debate was actual and the textbook pointed out very real flaws with Rush Limbaugh's logic (especially if they were a real world example of bad math) I'd say that it makes perfect sense to include it in a math text book.
It depends on who is defining what is pornographic. To some of the swivel-eyed loons deep in the religious right, who are very vocal in these matters, all material depicting non-heterosexual people doing anything other than being deeply unhappy or being subject to a stoning, is pornographic. This means examples in textbooks that attempt to be inclusive can fall foul of their ire.
