I have found it fascinating reading this thread.
I am none the wiser about the different types of feminism, but I don't think it matters. In my mind, feminism is simply defined as equality. Of course you can break it down into what you mean by 'equality' and that can lead to a million other questions, but equality pretty much sums it up for me. I didn't realise that so many people read more into it than that and rejected it!
I have always been a feminist, but my perspective has changed over time. When I was a young woman in my early 20s, with no family commitments and the advantage of a stable loving homelife and a university education, the world was mine for the taking and I understood feminism to simply mean equal education/career opportunities and pay. I had a tendency (though was too well-brought-up to admit it) to pity SAHMs as being downtrodden or lacking in intelligence.
Fast forward a few years and my understanding has changed. Now I have children I understand for the first time why women would WANT to stay at home with their children, and although it is not a choice I would make, I am now able to respect that. For everyone I know who is a voluntary SAHM however, I know another who is frustrated by it but finds childcare costs prohibitive (and why do we see the cost of that as solely coming from the woman's salary, rather than the family income?).
Today I am single mother, with an ex that bears no financial responsibility for his children (either in terms of maintenance or cost of childcare); an ex who is free of any daily responsibilities so can live life pretty much as he pleases. I, despite continuing to work, find my career options severely limited by childcare issues. I would dearly, dearly love to have a 'wife' in the way that men have benefitted from for centuries. If I could trust my children to be with someone deeply committed to their welfare so that I could choose to pursue my career, what I could do! But I don't have a wife, so I make the best of the childcare I have and am resigned to a stagnating career until such time my children are less reliant on me and I can change things. From a personal perspective, I believe that childcare is a feminist issue (as it mostly falls to women) that is hugely under-tackled in discussing, along with the division of household tasks.
The reason I left my ex was due to DV. Prior to my own experience I could never understand why women 'just didn't leave', and while I felt it was very much the perpetrator's fault, I felt a certain impatience with the victim. Having now been through it myself, I realise how insidious this abuse is and how subtly it starts. By the time it becomes obvious, you're too far in to be able to see it with the clarity outsiders can. Fortunately, I managed to leave and have never looked back, but I have a new understanding of DV and would dearly like to see the law changed so that DV is dealt with far more seriously than it currently is.
Likewise porn. As an empowered 20-something who wasn't oppressed, porn didn't bother me. I saw no harm in it if the woman enjoyed it too. However, now I'm a little older and less 'sheltered', I've seen the damage that such objectification of women achieves. I know there are many people who can use porn without there being any negative connotations, but there are far more who use it as an excuse to objectify and debase women. Porn doesn't bother me anywhere near as much as the blatant sexualisation of women in mainstream advertising, however.
Sorry, that's very long!
BTW, can someone point me to the thread that explains about the different types of feminism, or recommend a book that introduces you to the different ideas? I'd love to broaden my knowledge on this subject.
