Thank you for this, Jenava! I have to agree with you about motives ... it is really sort of mean-spirited to pass judgment in a negative way. I try always to say something nice to everyone - I mean, isn't it so nice to be complimented, and why *not* find something positive and mention it? If there's nothing to nice to say, then say nothing ... but I still find that there is something worth noting in most everyone, and that it makes them feel good to hear it.
Having said that, I have noted that many women (perhaps men, too, but *that* I haven't noted and cannot address) still have a mentality that worked for them in high school, and which they've carried over into adulthood. If you do not conform to the group (meaning any standards not their own), you're pecked at, like hens who will peck to death another hen.
Fortunately, as adults we are better able to note the behavior for what it is, and overlook the meanness. However, it really doesn't excuse those who still employ the "put down" as a way of attempting to establish their own superiority.
Well ... off my soap box, here. :o)
