Why when you do screaming/vocal covers on youtube do pepole?

want you to do the headphone thing. i do scream covers and i cant edit my audio file to do that so i just use a Stereo why do people constantly ***** at me because of it and i like using a Stereo its just easier. my youtube is waterfall815 i cant link im at school im not bad but why do you have to do that i mean i live in hillbilly hell its not like i can get help and i don't want it but why do u people complain about just using a Stereo i mean really why does it matter
