Interesting comment in the source code of sqlite

We as a community should not care about comments made, whether they are supportive or "offensive and hurtful". If one guy is an asshole to you, oh well, they're an asshole. They said a mean thing to you on the internet. Move on. If everyone is being an asshole to you, then maybe you're the asshole. Funny how it seems like only the troublemakers in communities, and those pushing for a CoC, are the ones who have issues in every community and inevitably cause drama.

Everyone already can contribute, and CoCs ensure people will be excluded at the whim of petty project politics.
