So happy the discussion took a positive turn BH, as it was getting too contentious. Peeps, please dont judge any other jew, halacha is never cut and dry and there are always competing factors that must be considered. I know i made a pretty big chillul hashem (will never forget it) at a Skadden recruiting lunch when i was a fiery 1L straight from yeshiva. I walk in and there are the 2 blondest women skadden could hire waiting to greet everyone with their hands outstretched. BH i was careful not to even glance (let alone stare) at their fingernails, and with my head down i softly tried to explain that i'm sorry but per my religion i dont shake hands with any woman but my wife. they and the classmates around me gave the most awkward look for like 5 seconds, then said ok, they are sorry (these were recruiting people). my lunch was pretty downhill from there.
After that i learned up the sugya (this is actually a nice piece by R Gil
http://hirhurim.blogspot.com/2005/07/shaking-hands-with-women.html) and realized that there is what to rely on, and more importantly, the negative slight and misogynist implication is clearly not something that will make God's name great in the world (as our essential mission is stated), so in my personal opinion, after speaking with my rebbe, since then i throw my dead fish hand at every shiksa i see. if u disagree, thats fine, but dont assume people choose differently BECAUSE they skimp or follow ta'avah, sometimes people just weigh the competing factors in all decisions we must make differently (see R Chaim Shmulevitz's opening on Aveirah lishma, really important on this topic).
