Why waste bandwidth reposting something you won't defend?
(A trump card you either can't or won't defend)

I commented on your previous post and you shrugged it off
with an "I didn't write it".  

If this piece of logic is worthwhile posting twice
let alone once, then you apparently belive it 
should be willing to defend it. Herea are my comments

Why yes, tired of such simplemindedness like people who speculate 
without abundant, valid evidence (while claiming absence of evidence
doesn't "prove anything), fail to erect falsifiable hypotheses, 
and who fail to test their hypotheses.

But why let such a minor problem bother speculation?

Non sequitur, science doesn't prove anything and trying to prove 
a negative is an exercise best left for invisible pink unicorns(tm).
(Proof of the non-existence of invisible pink unicorns(tm) is left as
an exercise for the reader).

Is it just me or is this entire argument circular and "intentially 
based on a lack of evidence"?  Again, science doesn't "prove" anything, 
so the sentence "some people claim that the fact that there is no 
evidence proves something" is fallacious and non-scientific.  Second, 
this "logic" claims that it is ok to reject "an argument from silence" 
for *lack of evidence*.  In effect you're saying it's ok to reject 
arguments based on *no evidence* for *lack of evidence*  If this is 
so, then why can't other arguments be rejected for "lack of evidence?"

You have to have some data before you can interpret them.

A few of which are: Don't hypothesize without evidence; erect testable
hypotheses which can be falsified; test your hypotheses.
