Because once due primarily to mod abuse qualifies as "lots of times." If you're going to result to ad hominem to argue, at least try to get the facts correct. Simply put: two years ago, I would've been banned in this thread already for the same exact posts. Context matters.
Ad hominem #2, and the construction of a straw man. I never said body language does not exist. Don't construct arguments for me, especially ones I disagree with, just because they're easier to refute than what I've actually said.
Re-affirms straw man, ad hominem #3.
Pointless anecdote. To respond to this anecdote: people don't verbalize their feelings for various reasons, however if we're talking about friendships or relationships, a lack of verbalization is generally a failure in communication, which more often than not leads to a failed relationship. And the science demonstrates very consistently that this doesn't mean you can discern what they internalize from body language alone, or even a tiny percentage of it. If this were the case, our intelligence agencies would be able to do far better than they have in the past. Further, even if you were able to infer much from someone via body language, you make a fairly big mistake by assuming everyone is the same or that your reading is accurate, which can actually complicate things more (such as the strong anecdotal evidence that people "reading" their significant other leads to unnecessary, baseless fights that are more often the result of a lack of communication, but not what they are accused of).
Pointless anecdote #2. As an interesting fact, what you're doing here sounds more like a psychological evaluation than it does "reading" any sort of nonverbal communication. Here's an interesting read: Psychological sleuths--Criminal profiling: the reality behind the myth
Another pointless anecdote, but I'll respond in kind with a contradictory anecdote. I have gone through a job change recently, and very little of the integration process was nonverbal, it was very much just getting to know people by actually talking to them. That includes a significant amount over chat-only protocols that completely preclude the possibility of any nonverbal cues at all. The face-to-face interaction serves more as a way of expressing common nonverbal communications (laughter, smiling, etc) and becoming comfortable with other peoples' mannerisms, which makes bonding and becoming comfortable with others much easier, which makes it significantly easier to trust others. None of this, though, has to do with anything that isn't extremely well understood and confirmed in science.
Ad hominem #4. I'm professionally successful in a career that requires me to successfully communicate and interact with other individuals, constantly. I'd say that contradicts the insult you attempted to make quite well, but also serves to demonstrate how incorrect your assumption is, as you're still arguing towards the straw man you constructed.
If you'd like to actually make a point, or refute anything I've said, feel free. In the mean time, I will continue to enjoy your personal insults. I'm almost out of popcorn though, so do hurry along. I really don't feel like going to the store.
