Now for double standards and general sexism against women
I find that men and women can both be what is defined as 'bitchy,' and most men may try to define themselves as assertive, but most people would prefer the word 'dick'. And the reason why a woman might be defined as 'nag' because generally a nag is either A: A parent to a lazy child or B: a person of equal or inferior position acting insistent that their ideas are superior apart from their real value and women tend to be in either roles a great deal, thus definition comes up more. I've told my brother to stop nagging me when I've been playing a game before, so hey. Stud/slut is starting to change. Slut is either gaining a better meaning to people or men who are particular to playing the field are gaining the title of manslut and shamed equally; though which depends on the area and person. I tend to dislike the 'play the field' types, but hey. I think Articulate and Chatty have completely two different meanings, and I've never had any gender connotations with them. Someone who uses a wide vocabulary is articulate and someone who is chatty is someone who talks to talk. Women tend to be more prone to chattiness due to social constructs while men tend to try to be articulate to seem 'superior,' but that's a different double standard that defining the same term differently.
The breast feeding stuff and the cosplay stuff I'll agree are pretty strong double standard.
The final one though, well. Main question is with that "Do men and women have the same reaction to see the chest of the opposite gender?" As a bisexual, I have a much stronger sexual reaction to female chests than male ones, though both inspire some reaction. Sexual reactions in public tend to be discomforting to some. If it's cultural inertia? We need to go slow, but make the shift. If it's more biological, than there's probably good reason why a woman should wear a top. Though I know in the past men wore swimsuits that covered their chest and thighs.
