If you have criticisms of this question, please state them plainly in the comments.
I mean the question literally, and raise it because I am very curious as to why it is that some strange ideas about gender issues are so compelling to many people. It bothers me that I don't understand it. I also do not yet understand why many others do not share and possibly do not understand this curiosity. This seems to me like a big hole in my understanding of human psychology, and I am not content to leave it unfilled.
I say this because a number of people have assumed that what I meant by this question was that feminism is a bag of clearly irrational ideas, and that my intention in asking it was to invite people to bash feminism. If that had been my intention, it would have been a spectacular failure, as instead several people have bashed me for allegedly bashing feminism, while no one has responded with any feminism bashing.
What do I think of feminism? It depends what is meant by the term. It's one of a number of terms for which I have no default definition but instead always ask people who use it in conversation with me to tell me what they mean by it, as I don't think it's possible to predict this reliably enough. There's no common understanding of the term known to me by which I think that feminism is mainly bad, and I think that by most common definitions feminism is good, but that it would usually be more helpful to use different terms.
Even if feminism was a bag of clearly irrational ideas, though, I would think very poorly of feminism bashing.
And I think equally as poorly of feminism-basher bashing.
