It is ridiculous how many people do not get this movie
"When they get to her new place, the owner is home and he kisses her on the mouth. It’s clear Stephanie has some sort of relationship with this guy and Tony slut shames her over it. She cries and cries, because she has to repent if she wants to be a good girl."

First of all whoever wrote this totally doesn't understand that Jay made Stephanie become his little sex toy in exchange for help with her career (very similar to the Harvey Weinstein scandal). Secondly Tony didn't "slut shame" her at all, he got her to confront her situation and realize what it was. Before the moving scene Stephanie was putting on this snobby bitch act to hide the horrible things she had to do to get to where she was and it wasn't her. Tony was quite possibly one of the few men in her life who actually cared about her and didn't just want sex out of her (I agree though his behavior later in the car was unacceptable and he did admit he behaved horribly and asked her to forgive him).
Then the author is too dumb to realize that Tony tried to keep Annette from putting out for the group but she wouldn't listen. Annette while I agree Tony should not have called her a c-nt was using Tony, she just wanted to be a "married sister" and Tony was a means to an end for her. They were both jerks to each other.
Finally yes there are some racist and sexist terms used in the film: THAT'S THE POINT! We the audience are not supposed to agree or condone the Bay Ridge Scene that Tony is a part of, that is why we support and sympathize with him at the end when he says he wants to get out and lead a better life.
I swear SJW's are so freaking stupid.
