"Google wants all users to feel represented in its emoji selection. The search giant has launched a set of 53 gender fluid emojis as part of its broader push to be 'more inclusive'. Gender fluid emoji have longer hair to make them appear neither male or female."

"Lots of animals engage in homosexual behaviour, but whether they are truly homosexual is another matter entirely"

Apparently, all of the Animal Kingdom needs the potential label of "gender fluid".
An aside about grammatical problem of "all is" vs "all are" (re: "All of Animal Kingdom") ...
Re:

Since this article suggests that both forms are correct by popular usage,
we might proffer that sentence context also determines the proper form.

"Say what?!" "All is/are" is gender fluid grammar (what they say you see is what you get).

Compare: "All you need is love" vs "All you need are love".
Even the Science Tech article uses both forms: "53 gender fluid emojis", "Gender fluid emoji"
and hints that an explicit number of things determines the Object's contextual plurality.

Apparent grammar guide: Is the Subject things (plural) or a set of things (singular)?
If this is unknown, attach a gender fluid emoji to clarify your sentence.
