This reversal was requested by Matz, who stated:

  I am sorry but I am confusing. As a non-native English speaker (and non-USA citizen), I have a hard time grasping the issue.

  Of course, I am against any kind of harassment but I am not sure how those changes improve the situation. Probably we don't share common sense, background, and culture.

  So I propose the following:

  * Revert everything back before the issue for now
  * Protect related PRs (including #2690, #2693, #2695, #2696) for a while (say 1 month) to cool down
  * Then open a new issue to discuss the CoC for the Ruby community

  Note that the Ruby community has no membership, no initiation, no admission. It's just a group of Ruby users who like the language. So the community guideline shall be abstract and vague (with encouragement but without enforcement) like the current one. CoC for individual teams (e.g. the core team) or aggregations (like conferences) might have more concrete CoC.

I get why the "protected classes" line was replaced with the better one covering all harassment, but why the hell was "fire breathing wizards" put back in?

Because it's funny.
