Red Hat fails to take WeMakeFedora.org

Very few people truly believe that a project should have no rules that govern conduct, but the debate is not about having to follow rules in the first place. It's about scope and enforcement, and the problems that can occur when rules are poorly thought out, hastily implemented, abused, or overused.

The issue isn't the CoCs exist, but how they're sometimes implemented. I don't doubt that there are people who want to make it controversial in bad faith, but you shouldn't make the assumption that anyone who is concerned about a CoCs implementation is the same type of person who would mob someone on Twitter and threaten them. In general, there are very few examples of harassing or aggressive behavior that were not grounds for expulsion before codes of conduct became popular, and as another commenter pointed out, small-to-medium projects may function fine without CoCs (or extremely minimalist ones), whereas larger projects may benefit from having stricter rules.
