This begs the question of who decides the rules of an organization.
I want to attend events with rules I like - I might like them because they're fair, I might like them because they ban symbols I find offensive.
Ultimately, it's up to the organization to define the rules, and it's up to me to decide if I want to attend an event with those rules.
defen points out that when these constitutions tread into topics of justice, they would do well to consider how to set up a fair system and what common mistakes to avoid.
This is a reasonable point and should not be at all controversial. Do you want fair treatment?
