I think it's important to separate: The way things are, the
   way they appear to be, and the way they should be (or should've
   been).* All three can be entirely different things. In male
   culture, I'd render a guess that most men grow out of the "are
   you hitting on me you fag" by 6th grade.* It started in 3rd
   grade when fag=girl=nerd=weird=whatever. By 6th grade, we know
   the different perfectly well and only the sad cases continue
   believing that stuff. When you here a guy talking like that, the
   typical response is something like, "I'm not hitting on you.*
   Are you repressing your homosexuality?" and getting all Freudian
   stops the elementary school implication in its tracks. I don't
   think guys beyond middle school care about the size of each
   other's dicks either, and even then that's just from inadequate
   education, which schools are trying to fix.* It's the
   (stereotyped-view here) female culture that tends to think that
   men care about dick size.* Well adjusted men don't care. Or
   maybe they do and I'm the minority, I dunno.* But I think most
   men grow out of that stuff. Let's see, male culture and reading
   intent: I'm trying to think of where we use it... well, it shows
   up in court rooms; lawyers try to sway a jury by trying to show
   intent or lack.* Police use profiling to form intent and use
   various rather questionable techniques for determining intent
   from a distance... causing much unnecessary drama imho. AH yes.*
   where men use intent: When we defend a loved one against
   perceived threats.* "Are you hitting on my wife?" Or if the
   loved one is money, we try to determine intent in business
   relationships. Trust/mistrust, mind-reading... you're right..
   it's something we all do to some degree. I think though, men
   tend to form a "baseline" opinion about a person.* If we think
   somebody's "got their back", we trust that they do. If we think
   we know someone, we assign intentions accordingly. I don't think
   we expect baseline intentions to change.* When we have formed an
   opinion about someone, I think men tend to stick to it, for
   days, weeks, months, years, decades to come. Women do it too;
   especially with their children, but I think overall, unless
   there's a perceived threat to the relationship (a new man in a
   girlfriend/wife's life.. or a business partner acting
   suspiciously.. then intent is questioned. Otherwise, I think
   most men assume, "has my best interests at heart". Female
   culture is a little more war-like in that regard.* I think women
   tend to feel they have to be on their guard more against
   perceived threats against character, men tend to be more on
   their guard against perceived threats against stability. But I
   could be entirely wrote about some or all of this.* Corrections
   welcomed.
