My opinion: you were all once a newbie. U shouldn't make fun because it is just like making fun of yourself since you were in the same condition as them :) help newbie become pro and make them encourage you :)
NO, JUST NO!!! They are still learning and going through the same experience as the pros had once. It is just like making fun of your past self but to someone else! >:OOO aaAGGHHH *le flips table* no :).
