Because micro evolution is changes within a group ,family,or kind. We believe in diversity within a group and that is observable .
Then feel free to identify the genetic mechanism that prevents the accumulation of multiple incremental changes over time resulting in a new species differentiated from it's ancestors.
If these small changes have some barrier, what is it?

Gene depeltion and the aid of natural selection.
Gene deletion is not a barrier to the accumulation of additional genetic information in incremental steps over hundreds of thousands of generations.
Fail.
