Reply to My Response to Luther

My reply seemed pretty good after reading it (i.e. i seemed to agree with Luther as i read... i was like Yea, Yea, Yea the entire time), but then there was some light shed on it in the discussion. Now, to be perfectly honest, i have no idea what to think. Why can't this whole thinking thing be easier, and the Professor not be so much the devil's advocate? This seems to be an impossible undertaking, which is fine because that is what thinking is, but its just so difficult. I just want an answer but a bunch of people have tried, and no one seems to be able to answer it... Are all the people to ever walk this earth just retarded?
