TBP and feminism have similar opinions, but for different reasons.

TBP, in most of it's stances, is concerned with the morality of the situation. Such as with dread and manipulation. They aren't concerned with who is being manipulated, but that manipulation is occurring. Or with negging, etc.

Unlike TBP, feminism is concerned only with the power and control of the situation, not the morals. With dread, or negging, their concern is men having a superior position or upper-hand in the situation. Because women are oppressed or the less privileged gender, this is wrong.

Another example is with abortions. Feminism doesn't advocate for abortion on the basis of morals, they do so on the basis of rights and power. Take this site for example Shout your abortion. The site is about women celebrating and spreading the word about their abortions. Every bit of it is concerned with the female acquisition of power over her reproductive system. There is no arguments concerned with the morality of women having the ability to abort.

This also occurs with rape and sexual assault. TBP approaches rape as a stance of "we stand against this because it's wrong to violate someone's consent". Feminism, however, defines rape as power and not sex. Feminism's focus on rape is amoral. They are concerned with the power exerted through rape, from men onto women.

This is why feminism commonly uses the concept of "teach men not to rape", because they focus on the idea of taming the power men have over women.
