Tim Hunts own inability to manage his labs properly (making people cry is not good management it's often indicative of bullying ) or control his own emotions when attracted to a colleague, is not a reason to prevent other people, who are possibly more emotionally mature and sensible, from working together. I've worked in a mixed sex lab and made some lifelong friendships, actually I was sexually attracted to one of the heads of the lab and he to me - We dealt with it, we joked about it and were careful not to be in a situation where it could become a problem - just as my then H dealt with his relationships to women he worked with in business.
Seriously, even when you're doing rocket science it's not rocket science to manage relationships - everyone has to do it in all professions. Labs are nothing special - actually, to be honest, scientists in academia are pretty tame unless it was all going on behind my back
