>“weirdness” is very relative to your local view.

I suspect it is entirely cultural, and 'weirdness' is a disgust response to foreign culture - not literally foreigners, but ways which are divergent from the norm. For instance new world explorers thought it bizarre people walked around nude - the new worlders thought it bizarre you'd cover yourself in heavy cloth and metal in the extreme heat and humidity. What makes those contexts "work" is groups of course normalizing behavior.

It could be a pure signalling behavior, or perhaps cultural 'evolution' at work, now that we have intraconnection on a global scale, people with divergent or novel cultures can link up and form meta communities that make them not a weirdo but an amabassador from a different peoples, even if the definition of "peoples" is so domain specific it encompasses, say, only those who religiously watch my little pony...
