Making it simple
Some people don't understand my posts. I will explain more clearly.
Pussy is an insult. Cunt is an insult. Bitch is an insult.
Insults are bad. They hurt people's feelings. Using insults makes it hard for people to understand each other. Using insults divides people into "us" and "them." These insults can be replaced with other words.
Pussy is slang for vulva. The vulva are female genitalia. (Genitalia are the external sex organs. The male genitalia are the penis and testes.)
Calling a woman a pussy says she is nothing but genitalia. Calling a man a pussy says he is a woman who is nothing but genitalia.
Calling a person a pussy is an insult. It is a sexist insult because it reduces a woman to genitalia. It is a homophobic insult because it implies a man has female genitalia.
Many people say pussy when they mean coward. That is insulting because woman or gay man is not the same thing as coward.
A woman is a female person. A gay man prefers sex with other men. A coward is a person who shows fear in a disgraceful or ignoble manner.
Cunt is also slang for vulva.
Calling a person a cunt is an insult. It is a sexist insult because it reduces a woman to genitalia. It is a homophobic insult because it implies a man has female genitalia.
Calling a woman a cunt says she is nothing but genitalia. Calling a man a cunt says he is a woman who is nothing but genitalia.
Many people say cunt when they mean obnoxious person. That is insulting because woman or gay man is not the same thing as obnoxious person.
Bitch is more complicated. A bitch is a female dog.
Bitch is also slang for a spiteful, overbearing woman.
Many woman think of a bitch as a tough woman who isn't going to take any crap from anyone. They think of a bitch as a snarling dog ready to attack.
Many men do not. Many men and women think of bitch as a submissive person who will do whatever whatever her master tells her to. They think of a bitch as a cringing dog whimpering with fear.
They think this because bitch is also coarse slang for a prostitute. It is often used in combination with the name of whoever sells the prostitute's services. A prostitute is called her procurer's bitch.
Using bitch to mean prostitute to mean obsequious person is insulting. Many women become prostitutes by force or from desperation. They may feel they have no other choices. Often they are forced to do things they don't want to do. They risk beatings, rape, and murder by their customers and their procurers.
The phrases pimp slap and bitch slap show how common violence is for these women. Some people think these phrases are amusing. These phrases are sexist insults because they make fun of beating up women.
The obsequious person does not risk rape or murder. Using bitch to mean obsequious person belittles these women's degradation and dangerous situation. This usage is unkind. This usage is a sexist insult. It is also a homophobic insult when it refers to a man.
Other words can be used in place of these insults.
A coward may be called invertebrate, spineless, gutless, spunkless; a craven, wimp, doormat.
An obnoxious person may be called a jerk, loudmouth, boor, lout, clod, blockhead, oaf, slob.
An obsequious person may be called a sycophant, myrmidon, minion, groveler, toady, bootlicker, lickspittle, brown-noser, ass-kisser, parasite, flunkey, lackey, stooge.
