I'm not sure it's fair to infer that, Trillian. I suspect that, like me, Alibaba is expressing her personal view - and just as vesuvia did with my statement, you are taking her personal opinion, referring to her situation, and rolling it out to cover every SAHM - and I very much doubt that was her intention.
It does feel as if any reason expressed for liking the term Mrs or disliking the term Ms is going to be misinterpreted as the poster saying something negative, if at all possible. I didn't say that feminists should only campaign for titles that sound nice to some people - I said that I didn't like the sound of the word Ms. Equally, Alibaba explained that, for her, Mrs acknowledges her role as a SAH wife and mother - I see nothing whatsoever in her post about being an unmarried SAHM being in any way less legitimate than being a married SAHM - but misinterpreting it to say that makes it easy to make her opinion look bad - which is unworthy of a decent debate, imo.
Fwiw - I can understand what she is saying. Having given up work to be a SAHM I do feel that what I do is not perceived as having any great status attached. I'm not advancing my career or using my education and training, i'm not bringing in any income to the household, and my working role doesn't have anywhere near the respect and status that dh's does.
I know that some people in society do believe this about SAHMs - I certainly don't, but it does nag away at me sometimes - that I am somehow a lesser person because I stay at home with the children. Note - I am NOT saying that I believe this about any other SAHM - I am far more negative about myself than I would ever dream about being about another person. Alibaba feels that, for her, the title Mrs gives her role some validation - if it helps her, is that a bad thing?
