I was like that for ages.
Totally shunned anything with the metalcore or deathcore label.
Glad I stopped being so close minded about it. I used to hate KSE purely because most of their fan base seemed like complete fuckwits, but I actually gave some of their songs a chance and really dug it.
Most of the deathcore genre of what I've heard is pretty terrible, but again, there's a few gems if you're willing to look.
You know, speaking of core, I think Stabbing the Drama is actually more appropriately called metalcore (aesthetically it's still "melodic death metal" of course) due to how it sounds musically and it's one of your favorite reference albums
(and one of mine now too, admittedly haha except you said you don't dig the music so I much, but I can dig most of that album)
