That's the key word: "Risk". Men are avoiding unnecessary risks (if they are intelligent) and avoiding women at work. Hell, they are avoiding marriage also, again, due to the risk - better than 50% chance of losing half your property and assets in a divorce that are more often than not, instigated by women. Smart men are also avoiding the risk of putting themselves in situations that could potentially be damaging to their careers and reputations. I know I do not interact with my female co-workers unless there are other witnesses or a camera present. A couple unfounded accusations have been made so far over the last year.
