Would you like experimental evidence of Lamarckian inheritance? See "Transposable elements as activators of cryptic genes in E. coli.":

The genome is become more and more Lamarckian each day. If that is your main objection, your biology is behind the times.
Lamarkian mechanisms were assumed by Darwin to exist. They have no bearing on the overall validity of evolution. The one you reference is pretty isolated in scope. Hardly the kind of thing envisioned by Larmark or his followers.
