I was going to put up a post about how MSNBC host Chris Hayes --
-- has one of the most punchable faces ever. He's soft, epicene, and exudes conceit. But a quick Google search of "Chris Hayes punchable face" yielded a lot of results, so this observation is obvious on its face, so to speak.
The search also led me to the Voat.co section on "Punchable faces." It's interesting to scroll through their list of such faces and see the common threads that run through them. A lot of the people shown are overweight, or at least soft-looking. And they all look extremely pleased with themselves.
It seems that at least part of what sparks the instinctive wanting-to-mash-their-noses-in reaction is the thought, "That person has no reason to look so proud!"
Another common thread that runs through the site is that a high proportion of the punchable faces -- though not all -- belong to Lefties. This makes sense: social justice warriors tend to be narcissists. Male SJW's also tend to have lower levels of testosterone, at least among whites. So they generally have a much softer look. And feminists tend toward obesity (which often has something to do with how they arrive by their resentment of men).
I've written previously about how Ted Cruz and Jeb Bush have instantly dislikable faces, so the political correlation is not perfect. But the correlation is real, and it's hard to avoid the conclusion that that says something about Lefties.
Scroll through that site, you'll see what I mean.
