I also can honestly say I rarely see this stuff personally, which in no way means I believe it's not rampant (way too many conversations with female friends and/or partners for that) just that I can't even recall the last time it happened in my presence. Despite being ready and willing to intervene I just don't have many opportunities to do so.
Which hopefully is evidence of at least some progress, when the creeps apparently no longer automatically assume other dudes are on board with their harassment and instead are most likely to engage in it when 1 on 1 or in the presence of known like minded douchebags.
Unfortunately, no, that does not mean what you think it means. What it means, generally, is that a dude will look at a woman who is with another dude and assume the woman is his, therefore off-limits. That is respect for the man, not the woman.
One way to recognize this is to hear from women how many of us have had a dude harass us when we are, e.g., standing alone at a bar, but then the man we are with comes out of the bathroom, and the harasser guy apologizes to the
man we are with not the woman herself for his behavior.
