The difference is that you're not the creator of Up.

This isn't an arbitrary ex post facto ret-con. This is someone finally feeling comfortable enough with who they were to tell the actual meaning behind their creation.

Jaded, insensitive curmudgeory doesn't make you a better person, you know. If you're lucky enough to know who you are, and to be able to express that identity without fear of harm, oppression or ostracism, then you could at least have the common courtesy to respect someone who—until recently—couldn't do so.

As you've shown, apparently I can't express myself without being insulted. So where does that leave us?

If being told to have some respect for others is insulting to you, then we're at an impasse.
