I mean a lot of people use to the term very loosely. All of a sudden they starting trying to pickup girls and they think they're a pickup artist. Sure you can make it a subjective term, but you can just as easily make it concrete. Just because you pick up a lot of girls doesn't make you a pickup artist. When you look at it in that sense and you say pickup artistry it implies using manipulative techniques in the arts of seduction and attraction to pick up women. Only rapist force a girl to sleep with them. PUA just make the odds strongly in their favor. Ultimately it's still the girls choice, but when you get good enough you basically manipulate them into getting what you want.

All in all, view the term however you want. I'm no PUA. I'm a guy with a set of morals whose looking to go out and meet new people. Whatever happens happens.
