Im assuming this isnt a real checklist on any form being used seriously, it smacks of the sort of thing my boomer boss will show me thinking its the funniest thing on earth.

It's a bit silly, because this kind of meme can definitely be interpreted as both a bigoted meme and as a sort of "ironic" kinda meme that is quite often posted in LGBT+ circles. It uses a lot of outdated terms like "Transsexual" and "Hermaphrodite", but then also has the more LGBT+ shitpost stuff like "pet walking on keyboard - Other". And indeed the absurdity of asking gender everywhere in the first place. I choose to pick the LGBT+ positive interpretation, but idk whether that's its actual meaning.

There's a little bit of absurdity in how people tend to make up new gender and sexuality definitions every day just to feel special. At this point the + in lgbqt+ is likely hundreds of different genders and sexualities. 'Gender' is now an identity politics game. If you want to play it that's fine a new gender or sexuality definition isnt hurting anyone but let's not pretend it isnt getting a little out of hand.

I've seen it like Michael pushing diversity training sessions onto the office (US) in the first season. Complete misunderstanding and absurd enthusiasm. I bet he would spend a night educating himself about gender and sexuality on the first resources found in google.

Listen, Dwight. Why would you put a sign saying MALE over your desk?

I insist on keeping it. We, Schruttes, are born Schruttes first, and everything else is out of our concern.

But why? Even Jim picked his new gender. Thrice this lunch, actually. Why don't you play into it to make our space more friendly for gendered people? Just for a day.

But...

You've heard me. Go take a break, and return with a new gender of your choice!

Next scene: a table sign saying GENDER-CONFORMING AMAB DWIGHT KURT SCHRUTE

It a little bit better as a satiric sketch than it is as a boomer humor. Especially, if Michael gets ridiculed for this senselessness in the end, like it happens every time.

The real joke is not just simply giving folks a damn text box!

(Edit: I'm curious why I'm being downvoted for pointing out bad UI. In general, something doesn't have a short, fixed set of choices, it's inappropriate to use a drop down list for it. Simple as that.)
