Ha, my favourite quote about the 'friend zone' is, "Women aren't just machines you put kindness coins into until sex falls out." I find the concepts of 'friend zone' and 'nice guy' insidious. They seem jovial, but scratch the surface and you uncover a lot of REALLY twisted ideas about what a woman 'owes' a man.
To often, I see it get borderline (it not leaping past the border) stalker-ish. The whole 'I like her but its on her to notice not on me to say something' thing can get disturbing, especially when it combines with other attitudes towards women. Sometimes it's like the 'I paid for dinner so now you owe me sex' mentality.
In this cartoon, he pulls the 'but he doesn't respect you' line, and the point of that is he doesn't actually respect her either. Her feelings and desires are secondary to his, and the only reason he is being her friend at all is that he hopes she'll decide she can't do better than him and settle. That's not respect. And that's not even friendship, which is my other problem with the term 'friend zone'. If your only reason for maintaining the relationship
is a desire to one day get into someone's pants, you aren't their friend.
And as a girl who has had a lot of guy friends, it hurts terribly when you discover the person you've been thinking of as a friend for years just wanted in your pants and as soon as he finally got it through his skull that wasn't going to happen, he threw the friendship back in your face. Especially when you later learn he did some things to sabotage your other relationships
to ensure you were 'available' for him.
So yeah, in my experience, guys who talk about how bad it is to be in the 'friend zone' and worse, talk about how mean women are to put them in the 'friend zone', show a remarkable tendency towards being creeps.
Any one I've met in the friend zone is there because he's too shy, not because he has twisted ideas about women.
Could be you are operating under a different definition of 'friend zone' than we are.
