Maybe. Maybe the "reactionary attempt" would have been non-existent if the advocates weren't using sexually graphic material, as linked in the thread above.
Do you also think that teaching of sex ed should include videos from pornhub?
In general it seems completely okay to include the discussion of porn in sex ed, and thus to show actual porn in sex ed.
It might make sense show it separately to boys and girls, mostly because boys are behind in development (on average), so the discussion of it should be different, but also because of the expected questions, etc.
