Best Answer - Chosen by Asker: Well, maybe because they have nothing to do with theater... I've been wondering why some individuals have the wrong impression that fake-expressions are appreciated in theater. Yes, theater is an art which operates with fake facts, but its goal is to re-create life as it is, not to be a matter of laugh for everybody.
About the screaming statement... well, many "actors" are not capable of controlling their voices (they don't have a "voice education") and they want to be heard from the stage. Some of them might not even have a voice for the theater now.
Anyway, these persons are not real actors... just wanna-be stars.
