I have seen any number of bad relationship situations, and I want to provide the people at the receiving end of such things with arguments that they need to stand up for themselves.
One common way of attacking a woman is claiming her to be a slut. There is a way to deal with such claims. The best one is, “If the woman was not a slut, she would not be having sex with you, so better thank your lucky stars that the woman is a slut.” Attractive women will be attractive to men besides their partners, and it would take a lot for them to remain loyal. A woman who is willing to have sex with one man is also likely to be available for sex with any number of other men. With attractive, sexually willing women, there will be men going after them in droves, and it will take a will of steel for the woman to avoid the temptation. So if a man is accusing his woman of being a slut, simply say that he benefits from that state of affairs and that, if not for the woman being promiscuous, he would not be getting sex.
Another is claiming her to be a bad – even an evil - person. To people who say such things the correct response is, “Why are you with me?” If a woman truly was a bad person, the man could not wait to leave her. Instead he chooses to stay. And if you choose to stay, it is because you are getting something out of the relationship. And if you get something out of the relationship with another person, you are obligated to be good to her whatever you believe her character to be.
Another still is claiming that she is crazy or has a mental illness, especially disorders such as narcissistic and sociopathic. The claim that is made about people with these disorders is that they are bad and can only be bad. Of course that is wrong. Anything human is capable of choice; anything capable of choice can be good. This is as much the case for narcissists and sociopaths as it was for groups that have been demonized before, such as the Jews and the gypsies. As for the woman being crazy, she is in a good company. To come up with original contributions you have to think in original ways, and people who think in original ways will always see people portraying them as crazy.
These are the main ones I’ve seen, and I would like to see women who are at the receiving end of such treatment get a hold of such arguments and use them to help overcome the abuse.
