Believing that the teaching you how to be a good ally is racist and sexist (against white men, I assume) is probably why you didn't fit in great there. I read that whole slideset and there's nothing racist in there - unless you're counting the scenarios of "what not to do."
The slides didn't have the explicitly racist and sexist bits. Basically if you were a white guy, you weren't allowed to interrupt anyone and anyone was allowed to interrupt you. There were also implications that one should discriminate against white men when choosing who to hire, who to promote, and who to have speak at conferences.
So if the white male has some important information for the bottom line of the company, should he wait 2hrs for wonder woman to stop playing or go and 'interrupt' 10 women not working and be a bad ally? What a joke.
Yeah, people have meetings. People go to lunch sometimes, or have appointments outside the workplace.
If it's "stop the world" important and absolutely needs to be dealt with right now, interrupt it, same as you would any other break. Otherwise, deal with it like you would any other situation.
The ideology is not especially deserving of anything but ridicule, but I went through the slides and excerpted some particularly goofy stuff.
"Marginalized person: Any woman who wants to work for
pay for an employer"
"Oppression: The self-reinforcing system of stories, TV,
news coverage, police, and legal system stereotyping Black
people as criminals, that benefits non-Black people and
harms Black people"
What TV shows has the author been watching? For my entire life, at least 95% of the depictions of black people that I've seen on television have been positive, sometimes to the point of being pandering. (For example, if a show has a black character and a white character, and one has to do something wrong to advance the plot, it will be the white character, because that won't cause outrage, while the reverse will.)
"You are eating lunch in the employee kitchen when a
group sits down near you. One person comments
loudly “If I ate that, I’d be as big as a house!” A
higher-weight coworker is sitting nearby and can clearly
overhear."
It's not clear who's talking to whom here. If it's someone commenting on the lunch of a coworker with whom they're not sitting, well, I've never seen behavior like that in any workplace, nor have I heard of anything like that happening. If it's someone commenting on one of their lunch-mates' lunches, then it's none of the "higher"-weight coworker's business.
"Higher weight people face workplace discrimination,
particularly women, regardless of ability to do the job
Body size is falsely equated with virtue: self-control, hard
worker, in good health"
Body size is correctly associated with self-control, energy, and good health. The proportion of overweight people who couldn't reach a normal weight if they ate sensibly and exercised is tiny. The "healthy at any weight" meme is absurd.
"Black people face a much a higher bar than white
people during hiring (and in general), and white people
often get a pass or exceptions to the process"
Bullshit.
"A co-worker shares an article on your work Slack
claiming that white men are biologically more suited to
STEM careers, saying "I don't agree with all of it, but it
has some good points." Another co-worker replies,
saying that they disagree with the article but we have
to be tolerant of co-workers with different political
views because diversity of thought is important too."
Men are biologically more suited to STEM careers, on average. You have to be willfully blind not to see that this is true. Why does this make people so angry?
""Office housework" is necessary but unrewarded work
(taking notes, organizing parties, tidying, etc.)
People of color and women of all races are expected to do
more of this work and punished for not doing it"
Bullshit.
"On a company mailing list, someone writes “How would
you explain this [technical thing] to your grandmother?”"
Old women (and, to a lesser extent, old men) are much more likely to have trouble with technology than are young men (and, to a lesser extent, young women). Again, why does this make people so angry?
Intersectionalism is just borderline personality disorder in ideological form.
Half the stuff you called "bullshit" on have been scientifically tested (and proved) in reputable journals.
You're projecting emotion on your perceived opponents ("why does this make people so angry") because your dismissal of their arguments depends on it. If you instead took this discussion seriously, you'd lose the ability to be sure you were right.
I don't expect you to have a revelation overnight, but sit down and think sometime about why this topic is so scary for you.
"Half the stuff you called "bullshit" on have been scientifically tested (and proved) in reputable journals."
I called two claims bullshit, so I presume you believe that one of them has been proven. Which one? Citation?
I'm not projecting anything onto anyone. I--like many other reasonable people--am bewildered by the intersectional left's refusal to accept reality. They are in fact the ones who become enraged when you point out obvious truths, such as that men and women are different.
The topic doesn't scare me, but if the discourse in the West continues down its current path, intersectionalism could become a dangerous thing. The core of the ideology is resentment, and history has shown that these resentment-based ideologies often have horrific results. (See, e.g., the the Rwandan genocide, the Holocaust, the Russian Revolution, etc.)
