Wooow. This was interesting to catch up on.
First, no, most of us ladies do not feel that way. But to play devil's advocate, sometimes everyone has thoughts like this about people they work with. If you're in sales, you know exactly what I mean. You get that customer that is just a complete jerk, treats you like you're the dirt that he/she walks on, and you just have to grit your teeth and smile, all while imagining horrible ways to take them down a peg. I think that's all that was happening with this girl. Her mistake was giving voice to those momentary thoughts, which probably don't encompass her feelings about her clients most of the time. One hopes.
On the issue of her basically outing herself... that was not at all a smart move on her part, and yes, it is entirely her fault that people now know her personal information. But that's not to say she deserves what she's getting with people harassing her on her personal social media accounts. Just because she screwed up and outed herself does not give anyone carte blanche to go messing with her. THAT is entirely their fault. You don't blame the victim for being victimized. The most you can do is show the victim how they might have avoided the situation in the first place by being a bit more cautious. Whether or not she has a good attitude about things is irrelevant. She doesn't deserve to be messed with in her personal life.
That aside, her threats against another member, however vague, are entirely out of line and relevant. That is not at all okay and shame on her for it. There is no excuse to go threatening harm against someone you're arguing with online.
