I'm surprised they didn't make the list given the general popularity, but let's be real here, Goblin Slayer is honestly mediocre and Shield Hero has been spiraling down the drain ever since it started.

No offense to any potential fans but I do have to say how depressing I find it that any even remotely original anime are never getting a second season yet a million cookie cutter faux medieval European fantasy harems are greenlit every day. I get that they produce whatever sells but surely people will have to grow bored of the same thing being done over and over again? Surely...?

Why are people just accepting casters taking forever to pick their spells? They should preplan their turns during other creatures turns. If your wizard is spending 15 minutes to pick a spell, it's your DM's duty to tell them that they're skipping their turn as the character is too indecisive to figure out what to do, better plan for your next turn instead. If a player is consistently slowing down the game multiple orders of magnitude they either need to learn what their character can do and make snappier decisions or play a class with less choices. There is no reason to tolerate people wasting other players' time to the point it's making the game unenjoyable for them.

The "adventuring day" is a relic of times when your entire campaign was exploring a megadungeon and you ran from one encounter to another, back to back, all night long. But barely anybody runs their game like that these days and the rules just never caught up with reality. Some people suggest having a constant time pressure on the party limiting long rests, and while it can work, it also puts a straitjacket on your story pacing where balance flies out the window if you ever let up on the pressure. "Guys, the apocalypse is merely hours away" quickly gets old when it's been that way for months.

Well, that and 99% of the rules involve fighting or exploring. Anything the rulebooks have to say on social interaction boils down to "well, you just talk to the DM, and sometimes they might have you roll a d20, just figure something out". D&D isn't really so much a role-playing game as it is a weird dungeon-crawling boardgame with some role-play elements. Sadly, people are allergic to trying new systems so instead they'll just try to bodge the one big-name king of TTRPGs, D&D, into doing things it was never built for, forever leaving them wondering why driving in screws with a hammer isn't as fun as they expected.

The more I look into it the more I start to feel like it's entirely intentional. As OP mentions, the other forms of polymorph explicitly spell out you get to choose, but normal polymorph does not.

Also, while it's of course not directly related to DnD, there are some older dungeon crawling media that have both been inspired by DnD and been an inspiration to it that run with this interpretation. For example, in Nethack, a dungeon crawling game first released in 1987, polymorph is entirely random making it a gamble. At least DnD 5e caps the challenge rating so at worst you'd get another monster in the same ballpark strength as you had initially, in Nethack you could just as easily turn a goblin into a dragon.

Perhaps because people aren't going around calling others "males" to demean them?

These are not difficult concepts if you turn on your brain.

Female/male are used in English as adjectives when describing humans, but as nouns they only refer to animals. "She is a woman" and "She is a female actress" are both okay but calling women "females" is purposefully demeaning and sexist. I do not believe there is any regional difference in this, nor should we really care about such since there are no regions when we're on a global forum.

I'd rather sound miserable than incel.

While true, there are some languages that are the wrong tool for every job. JS is one of them. I've dreamt of a future where web frontends switched to something sane but instead we got stuff like typescript which is like trying to erect steel beams in quicksand. For web frontends I can understand that historical reasons have lead to this but whoever came up with node thinking JS would be a great backend language has a lot of explaining to do.

they preferred training females

It's "women".

Which is exactly why you shouldn't be using them in a situation that clearly calls for a switch.

And there are way too many projects where the documentation is nonexistent or bare to the point of being counterproductive to wade through. I've seen way too many open source projects that purport to have documentation but when you open it, it's just doxygen run over the raw source files with barely any documenting comments in them. If I wanted to see only the names of the classes and functions I'd just pop the source in an IDE, the point of documentation is to point out everything that isn't immediately obvious just looking at names and to give examples.

"Self-documenting code" is the biggest lie we tell ourselves to get out of writing actual, necessary documentation.
