Why the criticism for Pac not wanting to fight at welter

Pac can't going up in weight but so much. Notice that those who hate Pac do not want Void to fight higher. However, Void won't even fight those who are at his same weight! Cotto, Mosely, Williams, nor Margarito. Void even refused to fight Pac and instead wants to fight the lightweight champion.

So........using their logic, Void should fight Vitali and Vladimir Klitschko ASAP.
