Gadolhadorah, you are the one that read that theme when no one was implying that. Everyone who suported the OP simply said that a person needs to feel comfortable in the company of their guests, in a spiritual sense or otherwise, and it doesn’t matter if the guests are divorced or not.
Personally, I don’t get this inviting divorced women thing. In our Chassidishe community the women who are divorced eat at their own family’s Shabbos seudahs. Sometimes for Yom Tov divorced women do get invited out, but these women are already close friends to their hosts and their spouses are comfortable having them at their table. We used to have a divorced man over for some seudahs but he was my husband’s close friend and he almost never spoke to me or to my teenage daughters except saying “good Shabbos” in our general direction, saying “thank you” to me and inviting us all to his wedding. If the all guests behave like this, I’d say kol hakvod to hosting guests of the opposite gender…
My mother was divorced at a time when almost no one was in our community was and we ate by ourselves or at our grandparents’. It never occurred to us, and especially to my mother, to eat at other people seudahs and we would never have gone had we been invited out.
