A person can perpetuate sexism without meaning to. It is just a matter of getting people aware and encouraging them to actively think about whether any things they do might be making women uncomfortable, and to try to be considerate.
Using sexual language to describe a non-gendered object in the workplace is a different issue to sexism.
"That car is sexy" = Could mean sexy as James Bond. It depends on the car, and the tone of person speaking, and who is saying it. You can't automatically assume it is sexualising women.
You can discuss whether saying such things is appropriate in the workplace but what the original comment say is this issue isn't related to discrimination against one particular gender, unless one is prejudicing one particular gender to be more prone to being uncomfortable with sexuality to begin with.
"It is just a matter of getting people aware and encouraging them to actively think about whether any things they do might be making women uncomfortable"
should be corrected to:
"It is just a matter of getting people aware and encouraging them to actively think about whether any things they do might be making people uncomfortable".
The former is gender discrimination, the second isn't. The former subtly suggests women are more prone to be uncomfortable, and can, for example, worsen the bias a potential employer may have against hiring women, for fear getting into trouble with women being easily uncomfortable in the workplace, because they're women. I am aware of this bias in mind consciously, already.
Of course the meaning of any particular instance of language depends on context, but the most common case of a straight man (for this is about behavior by men, and most men are straight) calling something sexy without additional context is unlikely to be interpreted as "sexy like James Bond".
More broadly, on average, men who are used to operating in all-male social groups are less likely to have thought about, and more likely to do, things that would make women uncomfortable in particular than things that would make anyone uncomfortable, because they wouldn't have gotten (as much, or any) negative feedback in the past. Therefore, while one should be concerned with anyone's discomfort, it makes sense for such people to give special thought to the former. That seems pretty obvious; I hardly think it constitutes discrimination. (And of course, you could substitute any common descriptor for "all-male", and stumble on other real issues, but writing like the present article provides evidence that today's tech culture has serious dissonance with gender in particular.)
For the record, one could also argue, like the argument you originally replied to, that people already set on edge by previous discomforting events are more likely to be negatively affected by additional ones - i.e. women (in tech) are more prone to be uncomfortable not inherently, but because of externalities only partially under any given person's control. That is not discrimination either, but a reason to be extra empathetic.
I don't know if you've ever met a narcissist in your life, I have been involved with a narcissistic woman before.
And here someone describes the concept of a "mental filter".
"Narcissists install a mental filter in our heads a little bit at a time. Before we know it, everything we do, say, or think, goes through this filter. 'Will he get upset if I do/say/think this? Will he approve/disapprove? Will he feel hurt by this?"
A person can perpetuate sexism without meaning to. It is just a matter of getting people aware and encouraging them to actively think about whether any things they do might be making women uncomfortable, and to try to be considerate.
This sounds like a rephrasing of what a narcissist might tell me, suggesting everything wrong to do with her is my fault and my responsibility.
The suggestions of advocates of feminism remind me of many aspects of that experience.
If the important thing is to be pedantic, I guess you win?
But if we want to be pragmatic, we can acknowledge that many women, disproportionately, confront sexualization and objectification throughout their regular daily experiences and that this therefore suggests that sexualizing things unnecessarily effects them disproportionately as well. And since we're all very aware of this imbalance, it's completely reasonable to suggest that the behavior is sexist.
Women are one of the groups who have particular bad experiences in society in their day to day lives. Other such groups include the elderly, children in dysfunctional families, adults with abusive parents, illegal immigrants, the socially inept, the autistic. Each of these groups are disproportionately confront a specific problem aspect of society, every hour of the day.
If you want to be pragmatic about it - "have courage, and be kind".
