I'm not angry at all.
"nuclear holocaust kills bugs, thus it's not flawed. Its parts aren't flawed!"
You single out one part which may not be flawed, and then assume all parts aren't flawed. Did I say that? No. I said that some parts may not be flawed.
"This misunderstands "good." Good means a design of intelligence; when a genre steps outside of that, there's nothing good there."
You define good with a safe, general definition. What is a design of intelligence to you? Many argue here that Deicide is good; I argue against that. Intelligent people can have different (but yet valid) views on what is good. I'm just trying to cull your standards out of you to make recommendations for music you might like, not start an argument.
"And yet it all shares a similarity: it's rock/post-hardcore with some metal riffs, which wishes to impersonate metal and thus replace it
I don't think these bands/musicians are consciously doing this, do you? I think they're all just morons who don't know any better. Ignorance, not intended hostile takeover. Still annoying and gets in the way of good metal though.
"Like what? You named a behavior, not an attitude."
Well then that behavior is flawed, I chose my words poorly. My point still stands.
But let's cease this bickering, there's no point to it. This is a community here, we're supposed to give each other a hand. You want to know some good metalcore albums? Here's a few for ya - take them or leave them. (Apologies as I can't post Youtube links at the moment, laptop is on its last legs)
Integrity - Those Who Fear Tomorrow and Systems Overload
Today is the Day - In The Arms of God and Kiss The Pig
(ANUS labeled this band metalcore, not sure if I agree but....)
Discordance Axis - anything, but particularly Jouhou and The Inalienable Dreamless
If you like Discordance Axis I recommend checking out Gridlink too, grindcore; both of their albums are good, with Orphan being my slight favorite.
Rorschach - Protestant
I have found lasting value in these albums. They've passed the "5 year test", as I've had each of them for at least 5 years, and I still come back to them. Are they on the level of Altars of Madness or Consuming Impulse? Not quite, but then neither is Splenium For Nyktophobia or Close To A World Below; still great records. Hope you enjoy, or at least relate your thoughts.
