I’m not saying if participation is or isn’t high at the moment. I can only offer an anecdote. After my kid’s soccer practice I was talking to his 11 year old buddy from wrestling. I asked if he’ll be wrestling this year and he said, “nah, too revealing”. You can call it an excuse or not, but it is a stigma that our sport has and, at least in this case, participation could have theoretically been boosted +1 with a different uniform.
