I think he was angry at sucking and then being benched is beneath him. He was solely pissed at not playing, so he defiantly just sat on the bench. But between his wackanoodle girlfriend and other attention hitting him, he then knelt. But the attention for his defiance was already there and pinned in his ears - this way after a few weeks of sitting and not a word, he then started with his oppression crap.
I think his original intent was solely sour grapes, which evolved somehow.
