Non Binary / Gender Neutral

[MissBax]

Okay so I know this may spark some serious debate. I just want to say that I really don't want to offend ANYONE, however AIBU to say that the whole non Binary trend (for want of a better word) is getting abit out of hand??
If someone was born a man and chooses to transition to a woman or vice versa I understand that, but to say you don't identify as having a gender... I just don't understand it?! I am female but have never been girly - I didn't have dolls, I despise pink, and I always played football with the guys, climbed trees and was very sporty. But I'm still a girl. I know boys who didn't necessarily like "boyish" things but they're still boys. Any girl or boy can like anything they like.
Now we have "non binary" people who SAY they don't identify as one gender or the other, yet some of them are born female, wear make up and dresses. So following typically "girly" or "feminine" characteristics. Or those who have a sex change and THEN say they're non binary?! So then why have the sex change?!
AIBU to think this is just another way to ruffle people's feathers and possibly attention seeking?
(I wait in anticipation for being called ignorant and a biggot etc...)

Well, it's showing an ignorance of basic grammar.

Person A: "I went to see the doctor this morning"
Person B: "what did they say?"

Common singular usage.

Language is a mechanism to communicate and it should be as unambiguous as possible.

They is perfectly acceptable as a singular neutral pronoun when you don’t have details about the sex of a person. Historically the pronoun he has also been inclusive of male and female and more common than “they” esp where it isn’t clear whether you are talking about one person or multiple people and you want to make it clear it is singular. He” made it clear this was singular. S/he was a popular replacement for a time.

When you do know the sex (eg Sam Smith is a man) the least confusing pronoun is she/he, and therefore that is what should be used.
