I don't share any pity for Ryan, some people are just nasty pieces of work, you only have to look at his posting history to see that he revels in his bitterness and nastiness towards others. I do however think he lacks self esteem, and self worth, and this is why he displays the behaviour he does. It shows a lack of maturity, and suggests strongly that he is powerless in his own life. Not pity, just an observation of behaviour.
His posts have no value in any sort of intellectual capacity, as Ryan's posting style doesn't require any depth of thinking, but they do have entertainment value.
