Be nice to people. Respect and basic courtesy matter. That being said, she's not simply asking for that...she's asking and demanding attention, which no one is entitled to. If a man walks into a room to meet your friend, and he says hi to you and maybe even shakes your hand before talking to your friend...he has not wronged you. He treated you with respect.
On one hand she is laughing at men who demand attention from women, on the other hand she's crying that men don't give her attention. The hypocrisy is pathetic. She is morbidly obese and unattractive. It's not surprising men don't pursue her. Do I think she deserves basic respect? Sure. But she's confusing that with attention. I am not obligated to have conversations with women I'm not interested in. Will I say hi, how are you, have a good day etc? Yes. But that's not a conversation, it's basic courtesy.
