I fail to see the logic in giving advice to someone who has already condemned metal as bad.
You expressed no wish to learn anything about metal, your post purely stated that metal isn't good.
That, my friend, is in no way deserving of my advice. Why give advice to a wall?
Also, if your intention was something other than flaming, you did extremely poorly.

The funniest thing about your most recent post is that you make it sound like you're the victim when it was you who just talked out of your ass for no apparent reason. I mean, what kind of moron says that an entire genre of music sucks and then states 4 bands out of which only one is actually metal? It's so obvious that you don't even know what you're talking about.
