The feminist philosophers I know are of the rising generation, and they are very decent people whom I've not seen engage in poisonous rhetoric of any sort. Watching the destruction of the career of Prof. Rebecca Tuvel, however, I can't doubt that there is a problem of some sort at work in the field.
I wonder if it isn't a more general problem of American political philosophy, though. Typically, it is very human to respect those who live moral lives according to your sense of what "moral" means, and to respect people less if they don't. It's ordinary even to despise people who live lives that are immoral by one's own lights. The problem in political philosophy is that despising your opponents destroys the process of reasoning together. Yet we -- and not just feminists at all, but Americans in general, Democrats and Republicans and others as well -- seem to be locked into a cycle of despising as immoral those with whom we disagree politically.
Oddly enough there isn't a similar problem in ethics, at least not usually. There are several basic roads to ethics that are all thought acceptable even though they diverge. I tend to believe in virtue ethics, for example, and find utilitarianism to be fairly implausible. But I don't despise utilitarians. Nor do they despise virtue ethics, nor does either group despise deontologists. So it's possible to disagree on even the most basic questions of morality without falling into mutual disdain.
Probably it's just the question of power. In ethics, I decide for myself what is right and do that, and mostly that affects me and a few others who have chosen to associate with me (and are free to choose otherwise). In politics, decisions on moral questions are inevitably impositions. It's no longer a question of respecting a difference; it becomes a question of resenting being forced to accept things that you yourself find immoral.
I suspect that any attempt to redress this problem would also give rise to a complaint (again, from all sides) that it is ridiculous to ask them to respect people who want to impose immoral agendas upon them. Which means that their opponents must be driven from politics, somehow, since imposition is inevitable.
For 13 years now, I've been trying to convince people that the right way to resolve this is by finding a way for Americans of different moral views not to exert power over each other. Mostly I have argued for restoring the 10th Amendment and devolving powers from the Federal branches to the states. Then the power concerns fade, as there will be 50 different ways of living available to all.
Sometimes people can be convinced while they are out of power, but I have yet to observe many who remained true to the path should they gain power. It's a quandary: one must have power, and substantial power, to make a change like this. Having gained the power, though, why would you want to break up its very source?
