From my experience, there can be a lot of one-ups-manship in the office. Between men or between women.
If your environment has this type of atmosphere, it probably will escalate until you make it known where your line is.
I don't think it's a problem to make your line known. People, men and women, interact with others differently. Some of my coworkers are massive flirts for example, I'm not.
Their line is different from mine, and that's okay as long as we respect each other.
You didn't want to argue your perspective so you went full nuclear on people. And that full nuclear got someone fired, simply because you didn't want to have to talk to them. I can understand you may be sick and tired of arguing your perspective with other people, but I hope you've learned something as well here as I doubt that this was the outcome you were looking for.
I'm sorry, we just disagree. I'm the type of woman who will speak to people if I find their speech to be that distracting if I'm unable to move. These guys? If I was that upset? I would turned and said "eyup mates, can you keep it down? I'm having a hard time hearing the speaker"
I don't police their conversation, any more than I would like them to police mine.
I don't like passive-aggressiveness. I spent a lot of my life being passive-aggressive and always wondering why nothing ever changed.
If she was feeling that they were being inappropriate, there are other ways to handle it. I'm not a fan of naming and shaming without trying to handle it privately first.
Such as me saying I find the use of "chick" in that way to be unnecessarily derogative, but she really was out of line in my opinion.
