Splitting this off from "Shall not be infringed" because although I find this worth discussing, it definitely falls outside of parameters there.
Language is where the first battleground is. Orwell basically foresaw all this and warned us. It's pretty remarkable (or maybe not) that we got the warning so many decades ago and STILL things are coming to pass.
Orwell's Newspeak is a fascinating idea, a language that gets smaller every year, eliminating the very words needed to sustain undesirable concepts. Well, undesirable from the government's point of view.
But that's not really what I was talking about. Language is arbitrary, it's something that got made up. So let's do a little test. I'll say a word:
Dog
What came to your mind? Was it a poodle? A St. Bernard? Your childhood companion Spot? A tasty snack wrapped in a bun? And ugly person of the opposite sex?
You see where I'm going, so let's do another:
Ball
What did you think of? A tennis ball? Soccer ball? Testicle? Dance hall full of people in elegant clothes?
I'm willing to bet a box of .22 LR that no two people who read this will have had the same initial impression. So let's climb the ladder of abstraction a bit:
Love. Freedom. Honor. Rights.
We're getting into complex concepts now, and while we may be able to agree that both poodles and pit bulls are dogs, we may not be able to agree what constitutes honor. And what do we have to resolve this? A made up set of symbols we call language. Even though those symbols have rules, the rules themselves are also arbitrary constructs, and are expressed in the same symbols. My understanding of language is based on my upbringing, education, life experiences, etc. So is yours. The odds that we are EVER going to actually be talking about the same thing is pretty damned close to 0.00%.
In conversation, far less than half of the information exchanged is transmitted through words. Paralanguage, body language, proxemics; these all combine to carry the majority of the information. Language is almost unnecessary. Seriously, I just came back from a month in lands where I didn't speak the language, and I was able to get my basic needs and even convey humor just fine. A pointed finger and a smile go much farther than any words could.
So why the fuck do we put so much emphasis on this idea of the written word? Let's take a dodgy proposition to begin with (communication), hamstring it with arbitrary symbols (language), then then strip away most of the actual information, leaving the least useful part behind for others to try and interpret (written language).
So to say "Well, we don't understand what 'shall not be infringed' really means" is 100% correct. We don't, and we can't. Hell, the members of the committee who drafted those words didn't even agree on what they meant, not really. Maybe they thought they did, but they were mistaken.*
Discuss. Or not. Depends on what you think that word means

This may, at a glance, appear to contradict my stance in my other thread. Kudos to those who see why it doesn't.
