Sounds like a great way of excluding people from the workforce.
Apparently a lot of construction, extraction installation, maintenance and repair folk have a very bad time of i. Perhaps if they could get decent support in the work place that wouldn't happen. Though I suppose you'd probably conclude it's just natural attrition as the snowflakes kill themselves.
That's fine, but why do you think the culture should mould to your needs?
I think a professional work culture should generally be such as to allow the people who are capable of doing the work with the minimum ofaggression aimed at them. Controversial, I know.
Some dickhead flinging racial slurs at me all day doesn't make me feel that they have my back. Quite the opposite, actually.
You might argue that "punching up" is acceptable, or even that it's not slurring by definition (which I'd dispute), but membership of one "privileged class" doesn't automatically translate to actual privilege. (I think the feminists call this intersectionality.) In such a context, the labels of "privileged classes" absolutely can be used to punch down (e.g. saying "you're such a man" and slamming the door in the face of an impoverished gay transgender man trying to access domestic abuse services).
a derogatory or insulting term applied to a particular group of people.
It is inherent in the term itself, not in its use.* So it isn't simply anything that can be understood as an insult. All the stuff about "punching up" and so forth is beside the point."cisgender" has a technical meaning which is still it's primary use: someone who identifies with the gender they were assigned at birth (so it can apply to intersex people as well). In this it is like "heterosexual" and "male". Arguably it is not like "white", in that who counts as white is malleable, but for the most part whatever it is, in most contexts, "white" is not a slur either.
* I am in fact a lapsed linguist. I have a PhD. My specialization was in semantics and pragmatics. Semantics is meaning encoded in language. Pragmatics is meaning inferred from use: "it's cold in here" meaning "shut the window", for example. I am aware that one can talk more precisely and at much, much greater length about all of this. But this is Hacker News, so this is all I am going to say.
I'd say "white" is no more or less malleable than the others. "Male" has multiple, mostly-overlapping definitions; by extension, "heterosexual" and "cisgender" are likewise flexible, though "heterosexual" has additional flexibility. While the concept of "white" is completely ungrounded in base reality, as a cultural term (a description of how racists categorise people, and of who's affected by the consequences) it's relatively stable: the definition in Western Europe is completely different to the definition in North America, and the boundaries have shifted over the centuries, but contemporary racists in a given racism-domain seem to agree with each other.
How about let people say and do whatever they want amongst themselves and stay out of their conversations.
Dudes in dangerous professions bond by calling each other slurs which is ok because they're all in on it, such that if you can't handle some bad words how are you gonna handle the real dangers of the profession where people need to know you have their backs, so you're either not cut out for the job.
You as an outsider from the nice people bubble don't have a say in this to lecture them since you're not in on it.
