no one said hes never serious.
he voices true opinions all the time.
but he trolls probably just as much..probably more.
he baits you in particular all the time. all the time.
you hate him so much that you fail to hear the intended childishness that he sometimes includes in his posts in order to bait you.
hes said things on the level of, "i know you are but what am i," and he still gets you to respond.
regardless of whether or not what he said in the op was serious, this is bait.
he made an entirely new thread to address a comment that was said in yours.
thats bait.
continue on.
