Why is it so hard to believe he didn't have an agenda? Just because a bunch of college professors and other professions, desperate to rationalize their education, see
all that crap in other people's work, that doesn't mean the creators of those works schemed to advance some hidden agenda as part of a massive world-wide conspiracy.
Just like Shakespeare didn't set out to say even a minute fraction of the shit he supposedly said in his works.
"Ooh, someone's telling a story! It can't just be a story, though! There has to be an agenda because I seeeeeeeeee one! Burn him! Burn him!!!"
