Well, I'm a late blooming feminist, started out not even considering it, eventually became an anti-feminist, with a blog and everything, and finally my commitment to free speech and the realities of my experiences as a woman led me to a place where I engaged with feminist perspectives, and found myself convinced by the arguments. And so far, not come across anything to persuade me otherwise.
But I don't claim the label 'feminist' like a tribal thing, and I don't expect lockstep conformity from others either.
I'm largely second wave in my understanding, and my view of gender is informed by that, and I accept the Radical feminist position of women's oppression being rooted in our biology, and exploited by a society stacked to advantage those with a different biology, men, partly via the system of gender and partly by the simple physical threat of men.
Now, I came to this position through argument and experience. While I may well view people who dismiss or uphold the oppression of women, as individuals or as a class, with a bucket load of contempt on a personal level, I don't think that making a definitive moral judgement will have much of an effect beyond me expressing that contempt.
I don't believe feminism is an identity, I simply work for the liberation of women, from the perspective of being one in the period and culture I find myself in, and I will always prioritize women's voices over men's because the very essence of feminist thought to me is that it is for all women, even when I disagree with them, and that men have been in the ascendancy in every sphere throughout history, and they can butt out of this one.
