As far as I know, nobody can authoritatively say it's true. That's why it's called a "theory". I doubt that your so uninformed as to be unaware of the evidence.
Is there nothing about Darwinism that was and is wrong?
Define "Darwinism". I'm familiar with the theory of evolution. "Darwinism" seems a slippery term that defies formal definition, other than being a general perjorative.
The reason "Darwinism" has become a pejorative, is that many of the adherents of that viewpoint deserve it. They spin a theory as truth, ignore its problems, and muddy (and have seriously muddied) the scientific world with a sociopolitical nuance that simply never belonged.
