No. Criticism is valid. But only if it leads to alternative hypotheses that can be tested, and then to testing of those hypotheses. That is known as "constructive criticism". What you are doing is known as "bitching".
Sorry, but your arguments remind me exactly of those used by communists. They also accepted ctriticism but only if it was constructive . Unbelievable. They used to say "Criticism yes, but only constructive one". You have to add your own solution of the problem, otherwise you was a saboteur. Consequently criticism was almost impossible.
It is interesting that "sciences" like marxism or (neo)darwinism require from their critics to be constructive.
Do you think it is normal procedure also in the area of real sciences like physics, math? Do not criticise discrepancies in the Maxwell electromagnetic theory! Yet physicists made computations (before 1900) and came to conclusions that this theory is unable to explain some phenomena.
It was Max Planck who gave explanation of them. According you physiscists before Planck were "bitching".
I could not answer, but should maintain my ground.-
