Natural selection as oxymoronic stand-alone term, can be no more a fallacy than the stand alone [[Pleonasm]] terms 'black darkness' or 'free gift' are , because only *sentences can be fallacies, tautologies or illogical''.
Is the contention that "free gift2" is a tautologytrue? . To assert that such a phrase always says the same thing twice is to miss-frame the particular premise of a user. For example: A man's gift of a dinner and a movie to his date may be a "gift2" but it sometimes comes bundled with expectations. But, if the recipient of the free dinner asks first "if I go with you, are you expecting anything?" and gets the answer "no", then it's accurate to say the invitee got a "free gift" of dinner. It is incorrect that no gift can ever have non-free implications attached to it, therefore the term free-gift is a
[[Pleonasm]] and not a tautology: only sentences can be tautologies. A tautology explains everything under all conditions,from the man providing a 'free-gift' is clear that the same sentence could in another context imply non-reciprocating behavior from the person receiving the gift. Thus the sentence doesn't explain everything in all contexts.
