For sure but I don't think you do your cause any favors by commenting that books about taking turns in conversation and understanding how to respond when a family member dies is imperialist and heteronormative without providing any context as to why you believe that. I'm sympathetic to your position but my immediate reaction was, "that's nuts." I went to look at the link and, while I saw some outdated language, and I wouldn't be surprised if some of the "Social Stories" hadn't aged well either, it was apparent to me that this was a basic educational tool that some children would really benefit from. And it's difficult to understand why you would object to that.

If you wanna help people to understand your critique I think you should add context and not use such absolute language. That can really only reach the converted. If you feel it is your civic duty to represent these values, perhaps it's your duty to represent them in a way that's accessible to people who disagree but are reachable?

I understand your passion, I sympathize with your position, and this is my attempt at constructive criticism.
