Paul wasn't hated because of his harsher and unorthodox methods.He was hated because he pushed his Pokemon beyond their breaking point,treat them like tools(even though the anime clearly shows them as intelligent),and was a jerk to everyone around him,sans the Pokequivelant of celebrities.Yeah,Infernape was the one who defeated him,but it just doesn't feel enough punishment.A better punishment is a rebellion of every one of his Pokemon against him-except his Electivire,who's as much of a jerk as Paul.
Of course,Tobias would be considered more of an a-hole if he had dimensions(he does not,so hatred to him goes directly to the writers).So,with rivals,we're stuck with a version of Silver that will never see the light,a hyperactive child,some musician and a plot device.I hope they make Trip less of a jerk.Of course,they've got a while for that,seeing as how he's only appeared in like a few eps
