Salmon change sex too if I recall correctly.

Is it possible to learn this power?

Do you guys like fish sticks?

For non-experts it generally falls into the "gay stuff".

(if you can explain the difference between sex and gender you're an expert)

The aquarium staff hoist the trans flag, and explain that "some fish change gender". The people complaining bring up "gay", but don't seem very well informed about human or aquatic cultures.

Am trans.

No. Unless you're joking about...The Gays~

Not trying to answer the question, but the only party that suggests that in the original post is "the haters".

Not technically, but a lot of queer people use it as an umbrella term. As the saying goes: we are all f_ggots in the eyes of the state.

“Gay” as a blanket term inclusive of all alternative lifestyles and peoples. Like how saying “you guys” is inclusive of all genders.

…or using the term “Man” to refer to all of humankind.
