I wrote a similar letter, my main objection was linking little girls (their products are aimed mainly at girls 8 and up) with a website that even MENTIONS sex, contraception, "reproductive choice" to use their euphemism etc. through the AG site. I may just be missing it but it appears to me that the link to girlsinc.org has been removed, though the organization continues to be promoted. It's not much, but a small victory nonetheless.
BTW I wanted to cry when the huge beautiful catalog arrived in the mail the other day. I immediately hid it so my girls wouldn't see it-hope my willpower holds out(I should've trashed it).
My 6 yo dd went through that catalog and circled everything she wanted. I'll have to hide it/toss it when she's not looking. What I'm finding out, is that AG is really no big deal to us. There are very nice dolls out there, lots of historical books for girls to choose from. We'll live.
