So what exactly would a "new-style" queer character look like? They can't just be talking about princesses doing action-manly-hero thing, because we already have that happening in Disney movies (Moana, Brave, Mulan, etc). Would a Disney Princess slip the words "my girlfriend Tracey" into every second sentence? Would it be a princess rescuing a different princess because of a "true love" curse? Would it be a same-sex kiss at the end?
They'd have to make it obvious. Because despite the fact that for most LGBT+ people you probably couldn't tell if they just walked past you (and you didn't know them personally), if Disney just made a character gay, or trans, or whatever, but didn't make it obvious, they'd just get criticised for hiding it, or not making it out there enough[1]. And if they did make it obvious (using LGBT stereotypes), they'd be criticised for stereotyping [2].
