I don't know that she's become a target any more than Foxfire was targeted. Political opposites, they have a similar style. Foxfire, too, left A2K after a particularly embittered exchange. I had very few interactions with MsO and the ones I had were always pleasant. I wish her well and hope that she decides to return. I imagine there are people who wish Foxy would return, if only to continue their diatribe against her.
My message to MsOlga is this -- there are many avenues of being true to yourself. If being here is a net negative in your life then you've made the right decision in stepping back. As you can see, there are many here who embrace you and miss you. Very few decisions in life are permanent. Stepping back from A2K certainly doesn't have to be one of them.
