If any woman or man say that men shouldn't be aroused by scantily-clothed/naked women, then they are saying it wrong. Or, you are hearing the message of some other feminists wrong. Being aroused is natural, but cat-calling, harassing and taking advantage/forcing yourself on the woman is it. This is the actual message, don't take women's revealed skin/sexy cloth or their closeness to you as an invitation for you to do anything sexual or forceful to her.
