This entire topic is absurd and not-even-wrong.
The context for the article -- the lens through which it is written -- is a fairly specific American / Western liberal perspective that I'm sure we're all familiar with. But if we (for the sake of argument) adopt this perspective, we will find that the premise of the article falls apart. "Gender," within this perspective, is a social construct unrelated to biological sex. There's a popular saying: sex is what's in your pants, gender is what pants you wear, and sexuality is whose pants you want to get into.
Nobody (again, within the perspective I am adopting for the sake of argument) disagrees that some sex organs are biologically male and others are biologically female. (They wouldn't use those terms because the use of "male" and "female" to refer to bodies has become taboo; they prefer to use "male" and "female" to refer to gender, but I trust the readers of this forum to understand my meaning.) So calling connectors male and female isn't a gender issue at all. Gender is entirely in the mind, and entirely unrelated to the body. But the connectors in question are entirely physical. They have no mind, and therefore no gender. You cannot ask a plug for its pronouns.
So the article is nothing more than an attempt to stir ####, or signal virtue, or to come up with yet another rule which all must follow lest we be branded cishet Nazi scum and thrown out of all respectable institutions and social gatherings. It's a way to feel superior, demonstrate in-group behavior, and ostracize people you don't like. Religious conservatives (sometimes, if they're bad people) do the same thing which I find delightfully ironic.
And the rules change constantly, so you have to be plugged into your source of truth (is it still Tumblr?) or risk using a word that was fine yesterday but is now "problematic." The threat of ostracism for unknowingly committing an offense is a very effective means of social control.
As an aside, I am in favor of trans and LGBTQ+ rights. Or whatever alphabet soup they're using these days; I stopped keeping track. (I have a separate rant about changing the flag from a rainbow to whatever the hell they're using now. For one it's a terrible flag, for two... no, no, I am not going to get started.) All humans get rights.
