I didn't say sexual harrassment will INCREASE. What I said is that the dynamics have changed, and different scenarios will arise. I think it's wise to think these things through and be prepared for a changed environment, rather than being reactive after the fact.
BTW: I heard on the news last night that before the repeal of DADT took effect, the military spent six months analyzing what the ramifications would be, and then six months training personnel in preparation of the change. I don't have the details of what got covered, but it does seem that they gave the matter quite a bit of thought.
