"My point was that Muslims are the first ones to criticism non-muslims and point out some usual things as sins."

Won't you say that Some People are quick to criticize others rather than saying Muslims are quick to criticize others?

This is what we have been talking about here. Actions of individuals can not be ascribed to groups. Otherwise, we can say that since you are criticizing Muslims unjustly, therefore (insert your nationality or race here) are anti-muslims.

Judge not lest ye shall be judged.
