You are still making assumptions. Your perception may be that all pornography portrays women as being subservient, and that this is degrading, but this is not necessarily the fact of the matter. If your argument is that specific types of pornography which portray specific women being abused or abased are degrading to the specific actors who are participating in the scene, then I agree with you. As to any generalization of this quality of degradation to ALL porn or ALL women, I must disagree.
