To scream sexist or to not scream sexist?

Lately I have found myself really picking up in little things that the men around me are saying, and I find myself wondering what is really behind this?

"I'm so glad you have a boyfriend to take care of you."
"I thought she was a really good kung fu artist turns out she is just a dancer."
"I want a girlfriend I just don't want a bitch."
""Stop being such a cunt man."

I wonder if they have any idea how disrespectfull they sound?
