The only thing I could add is that body language can be misinterpreted and isn't the same for some people. If you google, what rolling eyes means, it says "contempt", which is a fairly strong word for that. Also, leaning into a conversation and looking people in the eye is not always a threatening thing, I know I do this and it is because I'm interested in what someone has to say. I find people watching very interesting, but body language really can vary from person to person. Interesting thread.
