Because the schools would refuse to issue them.
that is irrelevant.
here is what would happen.
The schools would have the prohomosexual polics book and the pro-science view on sexual behavior. Rather than have the debate , both books might be scrapped or both books released.
Do nothing and they can say the science debate is over (ala algore) and dismiss any other views.
as it stands now, only one side of the argument ever goes out. we have conservative types, women in particular, who just go with the “born that way” falicy.
