The issue probably stems from the internet taking something that's real and extrapolating it to the point it's meaning is lost.
You're not friendzoned if she wants to be friends with you but has no romantic interest in you. That is life. Regardless of what you think is good for them, they have their own desires and things that make them attracted to people, just like you do. I'm sure most of you out there have female friends with which you have no interest in pursuing a romantic/sexual relationship with. Perhaps they're ok in short doses but you'd drive each other crazy long term. Perhaps you simply aren't attracted to her. Well, all that stuff? Women, as people, have those same kinds of thoughts. It doesn't matter if you think you're perfect for the job, she doesn't agree, and relationships are like those submarine keys, gotta both turn them at the same time.
The "Friend Zone" is, in reality, a very particular situation, where a woman, who despite being a person has parts of a thought process that are unknowable to man, "just doesn't think of you that way". It's not that there is any particular flaw in who you are, it's just that, "it'd be weird, he's my friend"(actual quote heard in the last six months). In other words, it's a situation where you have been categorized out of a relationship REGARDLESS OF YOUR PERSONAL QUALITIES.
It's important to remember that this is not nearly as common as the internet would like to pretend. While it's not RARE, per se, you also have to remember that she's just as likely lying as being truthful in those situations. i.e., she finds you deficient in some way/you're just not her type, but she doesn't want to just be a jerk to you, so she gives you the "friend" excuse to let you down softly (at least, in her mind).
In short, the argument would end if you didn't over use the term so that it loses all meaning and begins to encompass situations it was never meant to encompass.
