To me it is passive aggressive and it’s probably an extension of social media culture. People haven’t learned how to interact with strangers in the real world. Somehow humans figured out how to communicate their want/or not of a handshake for hundreds and thousands of years without a color reference palate. It takes something away from social interactions if your body language can’t do the talking and instead you just have some color label to express your emotions/desires.

Humans have mouths and ways to express their comfort level without these passive aggressive colors. I think this is more of an indictment of social media and younger generations not actually learning how to have appropriate social interactions with others in real life.

There is nothing weird about handshakes. Humans are social creatures and touching/embracing is part of that. Handshakes have been part of human culture for thousands of years. I think it’s more weird that people need these passive aggressive colors to let others know they don’t want to interact.
