Mormonism and the Watchtower are cults, not True Christians. They teach that salvation is found through their organization. Christians believe Jesus is all you need, and the Bible confirms that.
There ya go, now you're sounding like ISIS - HAHAHAHA.
Dude, I don't give two shits about your bearded sky daddy and why YOUR flavor of cult is superior to THEIR flavor of cult.
There's the "no true Muslim" meme, the "no true Scotsman" meme, it's all the same bullshit.
You do not get to be the arbiter of whose cult is the true belief.
Religion is like a PENIS.
It's okay that you have one, it's okay that you're proud of yours.
But do NOT run around whipping it out in public and if you try to ram it down my throat, I'll chop it off with a large knife.
