less expressive way of communication (read: words typed as text without the body language)

Are books less expressive than in-person communication? I'd say they're differently expressive.

If you can't see it, ask your manager. Or your manager's manager. Or someone who is actually using nlp or stuff like that. Or just grab a (any) book on psychology.

But of course, if somebody doesn't want to think on it because I offended his beloved toy for communicating, he will tend to argue endlessly instead. That's one of the most basic human behaviors: everyone is justifying what he's spending time on.

OK now you're just being rude

Yeah ok you're right. I apologize. It must have been a bad day.

I think blind people would disagree with your hypothesis.

There are many ways to socialize. I prefer some, but other people have vastly different preferences. If you're connecting with someone else on a personal level, I don't see how that's not social.
