Back to topic, I'd think boobs (and other parts of the body that aren't part of the face) won't have much impact on prefrences.
Would you really reject someone because of their cup size, despite their pretty face? Similary, would you accept someone just because of their cup size despite their less-than-pretty face?
I mean sure there are people out there for whom this may be a valid concern, but it won't for the vast majority. So the question then really only is where you draw the line - what about asymmetric boobs and other body features?
"Would you really reject someone because of their face, despite their excellent cup size? Similary, would you accept someone just because of their face despite their less-than-excellent cup size?"
Crudely termed, granted.
Of course the GP could be male too I suppose; not sure if that makes a difference.
"What about other body parts I find attractive?" isn't sexist. Or even, "I like boobs, what about those?" also isn't sexist (since it's explicitly conveying personal taste).
As it is, the original comment is crass. Probably more crass than sexist, I'll admit, but I promise you there are female readers here that probably rolled their eyes when they read the original comment rather than thinking, "yeah, what about that, that's a good question!"
Yes, crass. But it's not sexist.
Would we rather have an environment which attempts to make everyone comfortable, safe, and - unoffended and untriggered?
Or would we rather have an environment which attempts to give everyone the right to say what they wish, in the way they wish, without having to self-censor, and - quite possibly end up saying things that are hurtful or uncomfortable to others?
This question is at the heart of many disagreements in online communities. To me, in the past HN started off as a place where censorship and tone-policing was more rare, but as time progresses it becomes more and more an environment that is about tone-policing and preventing discomfort or offense.
I can't claim that either dynamic is preferable to the other.
However I do think there's a place for civil discussion and the idea that we're a social species attempting to all understand each-other, what each-other experience in life, and how we can all interact in a way that's collaborative is extremely important to our collective improvement, I think.
So sure, say whatever you want to say, that's your own right but it will inevitably cut you off or out of the collaborative environment some people desire to be a part of and work hard to create, that is if what you say isn't shaped in such a way to honor and respect other people's own individual experiences and preferences.
My words were intended to be a reminder and not to be taken as policing (even if I wanted to, I can't!)
I firmly believe personal desires and preferences can be freely expressed in a manner that honors the person holding them and also honors the possibly different preferences and desires of other people.
