This is well known.

Right wingers tend to be more attractive and intelligent, and believe in God. Support morals and ethics.

Left wingers tend to be less attractive, agnostic or atheistic, and have college degrees, especially useless degrees in "arts" and social "sciences." Supports relativistic moralism, which is a nice way of saying, will rationalize anything to support their world view. Even your murder always remains on the table.

"happy faces (both men and women) were likely to be representatives of right-wing" They hate us because we are happy.
