What genre are these bands?

Okay, I have been confused in a long time. What genre are these bands:
Some people said post-hardcore, some said metalcore, etc. Here are
some of the bands I have in my iTunes:
Attack Attack!
Chiodos
Dance Gavin Dance
Emarosa
Black Veil Brides
Escape The Fate
Hawthorne Heights
Saosin
Silevrstein
Senses Fail
A Skylit Drive
Sleeping With Sirens
Story Of The Year
Oh, Sleeper
Underoath
For The Fallen Dreams
These aren't all of the bands I have but I'm too lazy to write them
all. So can anyone tell me what genres these bands are? And please, no
haters and no dissing at my choice of music. Thanks in advanced for
the person who can answer this.
