I'd avoid it generally, as you just failed both your stated rules by repeating it.
That's an interesting and incendiary interpretation. Do you know for a fact that this person views women as prizes to be won or are you perhaps ascribing more meaning to the comment than can reasonably be inferred?
It is an impossible argument to make it you assume that the other party has a right to make a choice about who continues to pursue them for whatever damn reason they please.
How? There's no connection between what was said and the conclusion you drew from it.
arkh's post observes that women often apply different standards to men's behaviour based on whether they find them attractive or not. That's not really in dispute, it's the origin of the "hot women being attracted to asshole boyfriends" cultural cliche.
I'd dispute it in this sense: women, like humans of any gender, are more likely to apply different standards based on pre-existing status (e.g. whether they're friends already or not) but not to the degree that as a rule they'd welcome a sexual advance from one co-worker and not an identical one from another based simply on attractiveness, or that they'd consider the unwanted one harassment.
This isn't hard: women are humans and capable of rational thought, just like men. Your comment diminishes them.
This would directly translate to welcome a sexual advance from one co-worker but not an identical one from another based simply on attractiveness. Social setting (e.g. workplace) may drive the lower limit below skirting board for some individuals, but that does not make certain social settings universally irrationality free grounds where evaluation as potential mate has no effect on social (and even professional) interactions.
While both men and women are capable of rational thought, likewise both are not individuality, emotion and desires free.
Your comment reads to me as asserting that women are basically incapable of moderating their behavior based on sexual desire.
Viewing social interaction as a series of rules/steps to follow in order to "succeed" or "win" is how you view being attractive as a form of "cheating" or unfairness. This doesn't account for the other party having agency, since the only perspective taken is that of one side of a two sided issue.
Even in your post you say "women often apply different standards to men's behaviour based on whether they find them attractive or not".
Let's be damn clear: there are no different standards at play, there are two completely different behaviours at play - welcome romantic advances and unwelcome romantic advances.
Where did you read the word women in my post? I wrote about sexual harassment which can come from a person of any gender unto a person from any other gender.
The attractiveness also mean a lot of things to different persons.
A man who does not like tattoos may react differently to the same behavior coming from someone with a face tattoo or someone without.
But I hope you can reflect on how many things you unconsciously assumed from one comment and where it was posted and how it can relate to its content (double-standard due to bias).
We can move on, and now you know that this is a rather famous thing to say among people who are angry that women are allowed to choose who they wish to pursue them romantically.
1. Be attractive.
2. Don't be unattractive.
Two simple rules to not commit sexual harassment.
