Just a random example: I personally consider obsession with anime weird, but kind of cool at the same time. Are you sure that you cannot name anything you would consider both weird and cool?
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.
