'I accept that some people in the world are incapable of valid reasoning'
You have accepted that some people in the world are incapable of doing valid reasoning. (Such as some people in insane asylums that are totally insane and they cannot do valid reasoning about anything.)
Even if a Dr or Psychiatrist tried to tell such people that they were totally insane, they would be incapable of understanding what they were being told because they cannot reason validly about anything. So would you accept that such people would be unable to know they were incapable of reaching valid conclusions about anything?
