It's funny how cosplaying is seen as this weird niche nerdy activity... unless it's as an athlete.
Although, having said that, we do have the term 'full kit wanker' in the UK, for anyone who buys the whole kit (not just the t-shirt, scarf or hat). Because, you see, there's an acceptable quantum of cosplaying.
One thing has shaped communities and defined cultures for a century and the other thing is a science fiction show. It's really not comparable in my opinion.
Maybe for soccer, but the above statement could apply to basketball, ice hockey, and football and those have only been around about 2.5 times longer than trek.
It bleeds over though, they are all team sports. Just like Europeans grow up with their local football teams being celebrated, Americans grow up with their franchises being celebrated.
Yeah I’m a cosplayer and a sports fan. It’s weird. They’re really cousin hobbies. Both dressing up in appreciation and support of some pop culture “team”—usually that we had nothing to do with creating.
