zk – men (or women, or anyone) should certainly NOT be required to avoid any advances or personal relationships with others in their field(*), though they should be required to observe rules of reasonable politeness and decorum. People with the same interests tend to date, have sex, and occasionally even get married. Deal with it.
American society is way too Puritanical about the whole thing. And the Puritanism coming from the left is as bad as that coming from the right.
(*) – same field is insane. That would mean that two lawyers or architects couldn’t date, even if working for different companies. But I don’t have a problem with dating even in the same company — what goes on outside of working hours is none of HR’s business. (And, in fact, dating policies have been ruled as illegal as a violation of privacy rights.)
