What happened to being normal, getting to know people and then once having some sort of familiarity, maybe mildly flirting with them? IF they reciprocate, then go from there -- if not, forget about it?

Of course, if you're in a position of power over someone, you shouldn't do this or at least be aware of the consequences. But this culture of texting girls that are co-workers direct sexual or relationship stuff without even knowing them is just crazy. It's never appropriate.
