Why do you think there is such frequent reports of feminists taking actions that are counter-productive to the goals they are claiming to be chasing?
The reasons for the apparent self-destructive behaviors of feminism, like all leftist "ideology," are:
Extolling the demands of entitlements (desires) over the virtue of responsibility
Basing their behaviors solely upon their emotional state rather than upon reason and thought
Focusing upon perceptions rather than reality in formulating opinions
Feminism is a symptom of a disease that is modernism. As with any disease, it eats away the host from the inside, thus, the self-destructive and auto-cannibalizing nature of all leftist movements.
