Does "meme" mean "to be obstinate one"?

No, this has completely nothing to do with individuals & their belief systems whom of which you object to.
You're thinking of the American usage of the word "terrorist"
I honestly don't understand how you could mistake the word meme for terrorist, or heretic. (Or any other equivalent of the "obstinate one" idea really.)

I'm talking about memes. A series of ideas conveniently wrapped up in a box, & passed along to a series of individuals until it one day ceases to be a meme, & later graduates into a common belief amongst the world populace.
http://en.wikipedia.org/wiki/Internet_meme
is a phrase used to describe a catchphrase or concept that spreads quickly from person to person via the Internet, much like an inside joke

Memes are the ideas, & thoughts of others that get passed on as your own, ad nauseam. It's like a disease where an idea gets passed on, & spread around regardless of the individual's own set beliefs & thought patterns.

I'm not going to compare Megadeth to Fallout Boy, not because I like or dislike Fallout Boy (they suck ferociously horribly), but because Megadeth is NOTHING AT ALL like Fallout Boy.

Exactly. Which is why I bring up Army of the Pharaoh in relation to Slayer.
Slayer is as you said, Satanic. Army of the Pharaoh are a hardcore/horrorcore hiphop group that focus on Islamic Jihad.

I chose Alicia Keys, because she is more representative of what actual hiphop soul music sounds like.

Britney Spears is a horrible, and unfair comparison. Nobody who truly listens to R&B would actually pick out Britney Spears as the woman to represent their genre. (Alicia Keys would be the most likely candidate.)

I chose Immortal Technique, because he's a rapper with extremist socialist political views.

Where as Alice Cooper is the exact opposite and is on the side of the evangelicals. At least I assume so. Considering that he was a hardcore supporter of Sarah Palin. Alice doesn't seem to be Republican. So I figure it was her religious views that did it for him. (Or maybe it's that fact that she's a woman.)

I chose KRS, because he's just as relevant to the rap game as Megadeth is to metal.
KRS One - Sound of da police

When you see my comparisons you can actually feel that soul music has as much artistic integrity as metal.
IMO, Metal has way better instrumentals. Hiphop (At least the real shit.) Tends to have better, more politically driven lyrics.
Much of which gets completely misunderstood by people who don't listen to the music. (Krs's "Sound of da police" is rapping about corrupt policemen who run most of the impoverish neighborhoods.)

That shitty ass meme in my first post pissed me the fuck off, because of how hard it tries to distort reality of the two genres.
It's even more comical that you see this stupid meme constantly posted on Leona Lewis videos. A woman who predominantly sings Gospel & Soul ballads.
She's not exactly a woman who'd I'd label as pop.

LOL, here's another example of a small minded Metal head. (I'm a quasi metal head myself. I'm just hating on the retards who make all us metal heads look ignorant.)

dude fock off i dont listen to nigger rap and that kinda shit i listen to ROCK and METAL you know the real fkin deal, and if u call me a fag come to me ill kick your ass bitch niggers are nothing u need 15 of them to kill 1 white boy

What cracks me up is that he doesn't seem to realize that "Army of the Pharaoh" are in fact muslims, and THEY'RE NOT BLACK at all.
The entire group is composed of WHITE CAUCASIAN ISLAMISTS.
Yet, since Hellburst is a fucking idiot. He wrongly assumes that the Army are all Black *Nigguhz*, simply because of the genre of music that they perform.
Fucking faggot man. I'd kick his ass myself. I'm tired of these assfucks who claim to be Metal heads who in turn make Metal look weak by constantly shit talking & repeating their idiotic memes on random hiphop & soul videos.
