Which “left” are you talking about, noble? Feminists are OF THE LEFT.
As for your security-tolerance dichotomy, that’s a very simplistic line of analysis.
Part of radical feminist analysis is recognising and fighting against the means by which males as a class control and exploit females as a class — class analysis being leftist analysis — and that is by looking at how male violence functions to ensure female subjugation specifically and the need, in order for liberation to progress, for women and children to be protected from that violence. The RADICAL position there is NOT tolerance of violence.
What you’re really talking about the so-called left now being infused with neoliberal and postmodern beliefs in individualism above everything, so that individuals be free to do whatever the hell they please regardlesss of effects on community, including the community of women, and most particularly to pursue individual profit within a neoliberal marketplace where individuals are their own corporate brands. THAT is what you’re calling “tolerance.”
NONE of this is leftist. At all. In fact, it was born in reaction to leftist politics.
What do you think leftists have been fighting for, over the past 200 years, besides the needs of the people to be secure in their provisions for themselves and their families via taking control over those means by which such provision is made?
Where the hell do you place the labour movement — striking miners, say — on your tolerance-security dichotomy? On the RIGHT, for demanding job security?
