Replying all in one, because you seem to have a habit of sending multiple posts and that's frankly irritating.
That is one of the deepest digging posts I've read for a while, but alright.
So, they're all about relationships. Most books are. Why does it matter if, amidst the many books about heterosexual relationships she reads, she reads a a few from a same sex POV? I also feel like you're skewing this. Why can't you have a book written from a gay female character's POV? Surely that would be compelling. Exploring relationships via girl hood.
You're just making lists of genres and plots. It's not backing up your point. I could do that, but that'd get pretty boring.
My point is, in a non explicit book, what's wrong with a gay main character? Who might have a crush on another woman? Or another man? These things will come up time and again in most books she reads, if she's not reading classics. It might be gentle but it'll be there because if she is reading YA, those are the topics.
And how odd. I was taught all of those books in school before 13. My DS is 8 and currently working on a project for school about a "light" version of Macbeth.
And again, if OP's child hasn't explored romantic relationships in books yet, that's fine. The issue here is that OP didn't come and post "none romance books please", she wanted specifically none LGBT books. And you know that.
By preventing those topics even in an innocent way, you know full well the insinuation. She's trying to curtail topics; her tone and language say it all.
So I think we're probably done, because I honestly have no interest arguing with someone who will beat a dead horse just to be right rather than explore an actual argument.
