Overall, this appears to be a learning project for a middle schooler and his dad as well as a way for them to cover costs through affiliate links. While this might be a fun and useful way to discover new books, you should read the reviews and cross-reference your findings with parental or specialty groups like teachclean.com if you are concerned about the subject matter.
Ah, I was mistaken. I noticed that the links were tagged with "ref=" codes, but I looked it up and apparently "tag=" is for referral codes on Amazon.
I come from a religious background, and I support plural, open society myself. So same-sex couples are a thing, and people do that.. so they are free to do that.. as I am free to pursue a stricter social definition.
There are people on both sides of this discussion, that feel so strongly about their point of view, that they actively, definitely, without apology and sometimes by unfair means, seek to present, influence and be role models for children in formative stages of learning.
Therefore, on both sides of this topic, I believe that "open" material like books for children, that there needs to be safety and guidelines, in the clear open discussion, about what is in them.. for the parents, family and their social groups to make their own decisions.
Lastly, you are right, I added quotes around "Marriage" because in my tradition, Marriage means a sacred union of one man and one woman. I am committed to support "civil unions" for legal rights of same sex couples, especially high-stakes end-of-life things like medical authority and inheritance, but no one cares about me personally, these are large topics that are decided in a civil process. I support that civil process.
Why is it that we consider sexual topics the one line that needs parental consent to learn or teach about? Seventeenth century American Puritanism, mostly.
Parents should homeschool their kids if they want that kind of control. Otherwise they should trust the education system to teach this and do the research to know when they should be taught.
The idea that same-sex marriage is a "sexual topic" but marriage between a man and a woman is not is patently ridiculous and we need to start recognizing that it's a cover for a hateful ideology. If ignored we're going to see the repeal of not just Obergefell but probably even Lawrence within the next two decades.
Totally agree on the idea of same-sex marriage.
