I am far from being an adherent to all things that stereotypically define masculinity, except for one thing: a limp handshake. If I shake a man's hand and it feels like I'm holding an empty glove or greeting a mannequin at a department store... ugh. It almost says MORE to me than anything coming out of that man's mouth. Everything said thereafter, I'm grated by the idea that he's either hiding something or lacks the conviction behind his words. I'm not saying I need a man to break my hand with a vice grip-like grab before I can trust him, but a firm, respectful grip simply says "I'm engaged, committed to our interaction, and stand behind what I say." I mean, even if I end up not liking the guy or disagreeing with what he says, at least a firm handshake tells me "yeah, he's a genuine asshole," as opposed to a limp one which tells me "meh, this guy lacks the confidence to be a genuine asshole."
