Checking for vandalism means we check all edits, no matter whether they are minor or not.
if an admin fails to notice vandalism because he/she hides the minor changes from RC, I consider it his/her own fault.

Go back to the original question of the original poster.
"How can a anonymous user make Minor changes and how to stop that?"
I think you look at the situation of the English Wikipedia regarding edits by anonymous users. The question of Elly is about the Dutch Wikipedia. The speed of RC there is much, much, slower there if you compare whit EN. Everybody still knows more or less everybody. There are very few anonymous users. Mostly from a different Wikipedia for a interwiki-link or somebody who has forgotten to login.
The edits done by anonymous users must be checked because the have a high change to be a vandal. The edits done by resisted users have a much lower priority.
Because there is no option "Show only anonymous edits" the option the hide small edits is the best way to keep the list of edits to verify short.
