Wrong again. (If A then B) does not imply the contrapositive inverse (If B then A).
Well, it sure is a good thing that he didn't imply that.
Please wake up, as he most certainly did. His quote showed (If A then B), but he claimed (A=B) that requires (If B then A). Now do you understand?
Please note that saying the same thing twice won't suddenly make a statement true, or a question justified in any way.
Your A/B implication is completely unrelated to Raist's post, and saying it several times won't help.
Again, do remember that saying the same thing, just using slightly different words, does not affect their credibility, at least not in a positive way.
I suspect that you have some intelligence, but not the education regarding this logic error, so I'll spend some time trying to explain this carefully.
I'm going to use the symbols 'A' and 'B' to represent two things that Raist claims are equal.
Now A can only equal B if and only if both If A is true than B must be true AND If B is true than A must be true. If Boolean Logic we call the first the positive and the second the inverse. Please reference:
http://www.jimloy.com/logic/converse.htmNow just to show you where Raist's error is (though I really think you can find it for yourself.)
A='there has been a change in distribution of genes and alleles'
B=' evolution has occurred'
His quote from Wikipedia was (If A then B)=
'If
the hardy weinberg model is wrong, aka there has been a change in distribution of genes and alleles, then evolution has occurred.
His conclusion is A=B: 'evolution IS the change in genes or allele frequency in a population'.
This is a fundamental logic error. Until he shows that if B then A, or If evolution has occurred then there has been a change in distribution of gene and alleles, he cannot claim that they are the same. (BTW he'll still have to show more to be right even then, but let's give him one problem at a time, okay? Hint: the next problem will focus on "has occurred" phrase.)
As far as saying the same thing twice, I recommend it in any debate where your opponent tries to derail the topic. Getting BF back to the debate means not affording him the quarter to Goodwin this thread. I repeat it not to make it true but to hold a troll's feet to the fire.
