I think I'd find it politically too charged to show to my kids. I agree with some of what they say but I don't want my kids exposed to any insiduous pro-life anti-euthanasia stuff til they are a bit older and more rational. I'd prefer a secular source for this information, and I certainly do not want to be telling my kids abortion, birth control or euthanasia is wrong.
They don't really make it clear on their website that that's what they are about, and I don't know that I think that that's appropriate on something aimed at kids.
(eg they say- and you have to dig for this- " one of their missions is to Expose the relentless promotion of abortion, abortifacient contraception, and chemical and surgical sterilization in misleadingly labeled “population stabilization,” “family planning,” and “reproductive health” programs." .
personally that's not a message I want anywhere near my young kids right now)
