I'm calling out the inconsistency about what is child appropriate. Nothing Disney has released in the last few years pales as sexualized content that wasn't already pushed further in the parks. I watched the Making of Me when I had just turned six, my three and a half year old sibling likely took nothing away from it. I turned into a competent, functional adult.
Heteronormative relationships are allowed to be put on a pedestal, for some reason. I know the reason is entrained bias that most Western nations still broadly hold. The exposure to two cartoon characters kissing was pushing no boundaries, regardless of their genders. Particularly when parents basically teach their toddlers about gender and relationships all across North America without thinking anything of it. The presence of a predominantly black cast is hardly boundary pushing in Marvel Movie #20, but yet apparently it was.
Representation is important to reduce bias amongst future generations and increase empathy, understanding and support for people and minorities kids may be underexposed to in their early childhood years. Disney was and is an important bastion for that. They are also way more aware and keep things age appropriate than people are willing to recognize; and if they don't it comes down to unspoken bias, likely driven by their own under-exposure to minorities in their own early childhood years.
