One thing I noticed is that the focus of these is on gender-stereotypical portrayals of princesses. Is only the princess-themed content specifically seen as 'damaging', or is Disney content not featuring princesses also suspect?
Another detail is that a good number of the results you dug up seem to be reflections on interactions with the 'Disney Princess' line of toys and media which was launched in 2000, which would suggest that the most 'damaging' of this content is specifically 'post-2000'. Was there something about pre-2000 Disney content you had in mind that's especially damaging, that is not the case with the post-2000 Disney Princess line, or is it all garbage?
