I realize that not all feminists are man-haters who wants to take more than the equal share. However, communities like SCUM shows us that such groups with these extreme views exist; and they sometimes hold influences over politics or social services.

Even more frequently, they may preside in your own communities and workplaces. These might be people with whom you have to share ideas and collaborate, so you can't necessarily just walk away. Has anyone faced low-risk situations like these? How have you handled it?
