Why is it not also an option to change the way the workplace works? As another commenter already posted, assertiveness doesn't equal knowledge or importance. If our society tends to prioritize things like assertiveness in men and tends to see these characteristics as negative in women, AND if we see these things as necessary and good in the workplace, how doesn't this disadvantage women? Why do women have to change for the workplace, why can't we change workplaces to be better suited to people of different characters?

Because in a meeting of 20 people, it's not practical to constantly worry about people who want to speak but give zero indication that this is the case. Approximately nobody prefers passive-aggressive women to assertive women. If men get away with being pushy and rude more than women, that's a valid problem to address, but assertiveness has nothing to do with these things. Nobody is put off by a raised hand or a quick "excuse me".

“Other people in the world are inconsiderate assholes, therefore I should be an inconsiderate asshole to help my coworkers prepare for the inevitable. And if they can’t handle it, too bad.”

By the same token do you cheat at every game with your children to teach them the cold truth about society?

"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."

This is a very uncharitable and needlessly aggressive take.

The recommendation of «you shouldn’t let your quieter coworkers speak unless they interrupt their way into the conversation in meetings because that will set them up for failure when their future coworkers talk right over them» is a pretty uncharitable and needlessly aggressive attitude toward those quieter coworkers.

Raising one's hand to speak is generally taught in kindergarten and future coworkers will likewise expect that everyone mastered this basic skill. These days there are raise hand buttons in video conference software. When raising hand is not applicable, a quick "excuse me" is not considered a big imposition on either current speaker or person who wishes to speak next.

I used to be too shy to talk on the phone, coming to US from a country where I only had phone conversations with relatives by coming to a communication center at time prearranged via a telegram. I got over that and if someone accommodated me instead, they wouldn't have done me any favors, because things like this are generally expected and accommodations will not always be available.

I certainly don't give children participation awards for losing games played by the rules. There are rules for speaking in meetings, and they don't include passive-aggressive silence with no indication that you would like to speak. If you gave an indication through words or gestures, then yes you should be given a chance in a reasonable time.

Listening to the loudest voice in the room is often not the heuristic that finds the most valuable contributions.

And that is undoubtedly part of why "brainstorming" has been found not to be the best way to share ideas.

That's a non-sequitur, there should be only once voice in a room at a time and everyone should know how to request to speak next, for example by raising a hand. If people are choosing to not make contributions when they can, it's on them.
