"Everything" hasn't become sexual harassment. I've dated coworkers. I have been rebuffed by coworkers. I have even been under the impression that a coworker might be into me who was not. And--somehow--I have not been accused of sexual harassment. Maybe because I am respectful in my approach, cut it out if it's not appreciated, and never persist past being rebuffed.

The "misunderstandings" about which you wring your hands are weaponized against women in the spirit of "don't be hysterical". You're not being moderate when you express viewpoints like this. You're just rationalizing bad shit. And, judging from your sterling work throughout this thread, you know it, too.
