Ignorant opinions on the spirit world

Most people I know of who deny the existence of a spirit world
  have never even looked into it,
   at least not with an open and inquiring mind,
    and so their pronouncements on the issue
  mean nothing to me!

I'm only interested in the opinion of open minded experts,
 and, particularly, those who have had direct experiences,
  and therefore have something meaningful and informed to say.
 And that isn't: "it's all in the brain"-
  which any ignoramus with no knowledge can say!

I've been studying the afterlife and related fields for over 20 years
 and so I have no use for the superficial opinions of those
  who have no knowledge of the field and yet are happy to dismiss it all
 as human deception and ignorance!
