I agree that towel color is insignificant. Logical? It's as if they're trying to take judgement away from thsoe who are paid to judge.
Perhaps you're right about "color", it's really not a big deal, but the rest of it simply takes the field officials totally out of the discussion. No arguing, no pleading, no discussion about what words, symbols, whatever might be insulting, offensive, derogatory.
After you've done this "thing we do" long enough, you'll note that "one-ups-manship" is an ever present cloud on this game, and most other games young men play. Not always a bad thing, but one that can get out of control (and has in the past) real quick and get real ugly. The current rule
eliminates a ton of endless BS and provides a solid brick wall to reference.
It's not our choice, opinion, fashion statement or anything else, it's a simple, unambiguous, non discussable rule. A young man can wear all the dodads his heart desires, or he can play the game,
he just can't do both. Ultimately, the player is the one making the choice.
Learning that some choices come with consequences is a valuable life lesson.
