Weirdness almost by definition can't be cool. Or at least not actual weirdness. In the 50's a leather jacket and a motorbike made you 'weird' to the old folks, but incredibly cool to teenagers. Same goes nowadays, only the details differ.
If you consider an obsession with anime kind of cool then you probably don't consider it weird, at least not in the sense the concept is presented in the original article.
Something that doesn't get you marginalized simply isn't weird.
In my experience, people who adopt a subculture do so partly to cope with being excluded from the mainstream. This is not always the case, of course, but I do think it's common.
The members of the subculture may be weird in my sense of the word (i.e. for the general population), but they won't be weird within their respective subculture. Within the subculture they will probably just be cool.
Of course, me and my girlfriend are still well enough in touch with those things (also thanks to social media) that we can annoy our son by flossing and dabbing, :p.
Also, being a literal nazi.
"Actual weirdness" being refined to mean the set the author chose, instead of an independent rule. Circular reasoning, designed to compel the (weak) conclusion you'd been arguing toward.
Being unusual is not the same as being weird. Being unusual can in certain circumstances make you "cool".
There is no circularity, and you have yet to make a pertinent counter-argument.
Weirdness isn't like this. What was once weird now isn't, though we can't be sure it will stay that way. Conversely, what was once normal is now weird, though this might change too. This process will continue.
GP is saying that if something is widely accepted then it can't really be described as weird in the present moment. This fits the examples given in the thread, of how it _used to be_ weird to have certain characteristics, and now it isn't.
This might mean that we haven't actually become more tolerant of weirdness per se, we've just changed the definition of what counts as weird, and are just as judgemental towards 2020-era weirdness as the previous generations were toward 1990-weirdness or 1960-weirdness.
Being completely tolerant to weirdness would mean, to my mind, to essentially not think in terms of weird/mainstream/cool anymore.
Now of course there is spectrum, and I agree with the GP that a big part of this moment is “being yourself” so eccentricity and uniqueness _are_ factors that can make somebody “cool”, but with that the bar for truly being “weird” has also shifted.
To be clear, I’m not value-judging anything here. Back in high school I definitely rode the line between “cool” and “weird” myself! Was called “weird” to my face semi-often. Looking back I can see that I was fortunate to be a weird kid that was both athletic and rather good looking, so I was still allowed to hang out with the “cool” kids and date “popular” girls.
* the dictionary defines neither in the terms we are using here
