Mayorga-Vargas-Castelljo-Wbc situation

ok so whats up ,can somoen explain it to me..i read the main page and thought what a bitch Castelljo is for backing out and fighting someone who doesnt deserve a title show or anything right ow. I mena vargas just came back and ok true mayorga has not done that good but he is better to face Castelljo and more derserving now...so my q is this...whi is right here and who not. Because i was watching Friday night fights and the annoucner(forgot his name) started getting al pissed and saying this is what f**ks up boxing and something abotu Don King etc...so my q is who wrogn than?People think Vargas should fight Castelljo..or that he shouldnt be stripped cuz now i am confused. I am i wrong to think Castelljo is a bitch for backing out,i mean i dont mind seeing the winner fight Mayorga but i just dont think Vargas deserves to get a title shot and that Mayorga will get screwed if Castelljo gets stripped. And as we have herd from Vargas he has no intent on fighting Mayorga,he has not even mentioned him. I think if castelljo doesnt fight his madatory he should be stripped cuzthats the way ti is...SO i am i wrong or what and if i am expplain to me whos wrong and right out of these guys and the whole don king thing. *Confusing as hell* (thanks guys)
