I didn't know this character was suppose to be transgender. The only reason I know about this was yesterday I went on twitter to check on some of basketball twitter, and then Scarlett was trending. Thought that was weird, so I clicked on it. She seems to indicate the character is transgender with her answer.
It didn't seem like just a bunch of 14 year old cisgender white girls complaining about it. Though, I do wonder why that would matter if it was? Just doing a quick Google search puts the amount of transgender people in the US at 1.4m, as of 2016. Any movement in their favor is going to require a lot of people who are not transgender to get any traction.
I don't really think someone needs to be effect by something, to want to argue on the side of it. Empathy is important here. And I get people are over the top, and plenty don't actually care, but ignoring it seems really harsh and exactly the opposite of the empathy we are crying out for in the face of Trump. If that were the case, who argues for the young migrant children being taken from their family? Only other Hispanics from the specific region these families are coming from?
And I am of course not saying this is anywhere near that. It isn't. It's just a movie. But i don't agree with the idea that you can't argue on the side of others, even if you aren't effected. That is the general, "how does it effect me" situation with those that do not realize how important the current situation with the Supreme Court is. If they roll back LGBT rights, should non-members of the LGBT community not care or fight for it?
