If it is harassment, my guess is that there is more than one or two damning e-mails out there. While it is possible to have actionable harassment from a single act, most of the cases tend to involve a "pattern" or a "climate" (or some other buzzword they tell us at our annual mandatory harassment workshops).
It depends on what, if you will, is "everyday practice." If the locker room consistently does the bad language/hazing/actions/whatever, then that's exactly the problem.
I'm not a fan of the so-called "pussification" of America. (I hate those damn mandatory workshops.) But I see no reason why athletes should be able to get by with things the rest of us can't. Or shouldn't. Professional football locker rooms are places for adults; apart from jobs where you're training people to charge up hills against machine gun fire, IMO, there's no excuse for a workplace that resembles the worst of junior high school locker rooms in this respect.
IMO
And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
