Disproving A Negative Poem by James McLain

To disprove the assertion of a negative claim,
if the burden of proof when asserted is.
Does the lack of evidence claim,
in the absence of possitive evidence enough
to prove evidence of possible harm?
Is this a possitive assertion if you must assert,
a false made truth a claim.
Disspositive shift from the burden of proof
from the parties in response to a claim?
Or opens the door for affirmative defense,
when promotion is falsely made.
Do other parties that enter in debate,
confuse the truth if truth is falsely claimed?
