I think you're presuming a lot of things, there, chief.
For one thing, I don't read Vince's threads and laugh at him. I actually have a respect for Vince and the hustler he is, within his particular socio-economic circumstance. I find this threads interesting because they depict a very different life to me. Quirky is more my feeling about his threads.
Secondly, this concept of "dire need of being wanted" is flagrantly exaggerative, given the fact he does not post these threads particularly regularly.
Thirdly, you seem to assume that Vince has no idea that people make fun of his circumstance when it is more likely Vince doesn't give a fuck.
So you find Vince's threads interesting? They peak your curiosity? They engage your attention? That's not saying much. Vince seeks attention and he knows there are haters but also people that will follow him. Some people (which could be you) like seeing his threads as they get a "rise" out of a person struggling and yearning for acceptance. Some people like seeing people fail. It's a vicarious thrill. It allows us to get so very close to humiliation, to danger, to abject terror and yet walk away clean. Wow! This provides a great sense of comfort and security, power and control. It's such a high it can be addicting. This is why GetBig has people like you...and Skeeter, Be There, Wes, Walter, etc. etc. You fuel it and love being "better" that the Vince's, Shizzo's, Pumpsters.
When we consider pleasure-in-others'-misfortune as pertaining to minor misfortunes and involving our belief that justice has been done and that we are not responsible for eliciting the misfortune, then this emotion is not so reprehensible from a moral point of view. The conventional view, which severely condemns pleasure-in-others'-misfortune, stems from considering cruelty and sadism as prototypical cases of this emotion. We have seen that this view is mistaken. Now, would it hurt you or be hard for you to be nice for one week and not judge people on this forum?
STAY POSITIVE!!!!!!!!!!!!!!!!!!!!!
