Dude, the "Shadow in Our Blood" is totally AIDS, which affects everyone but is disproportionately common in gay communities. "Through Smudged Lenses" is about... well, you can figure it out.
This is a stupid exercise. DT's lyrics are gay-friendly, certainly, but they're not intended to be specifically gay.
I actually find that to be one of the simpler DT songs. In the beginning, it has the line "Turn of the century lies." What I'm getting from a brief glance at the lyrics is this: we suffer from older social ideals, stemming from our less enlightened times. In the age of communication, we are able to find greater degrees of truth. For example, think of what a shitty job news media does of actually representing the truth of events: things are twisted to fit a world view. In the internet age, I know more about my nation's history and I have more context for our present actions due to a global perspective. We are, as such, seeing through clearer lenses. When he says "I want to see you die", he's actually talking about older, small-minded thinking.
The giveaway is this: "No firewall will save you". Firewall, while also a real-world object, is a networking term for software/hardware which blocks network connections. Used for both security (by everyone), and also for censorship (China, Middle East, Australia).
It seems that you're right, or at least the lyrics are in that direction. So the message is not to see through smudged lenses... At first I understood the opposite ("so smudge the lens a little, muffle the voice, phase out the sound a while and let it go"), but I found contradicting some parts. I think that it is a kind of sarcasm ("How else can we move on?"). So TSL is a song against enlightened-narrow-minded.
Anyway it's not a simple matter.
