I got it. Since so few people are likely to see the conversation then I suppose it's okay for him to belittle someone in such a manner. If no one sees you behave badly, then all's good.

If someone involved in a public facing project open to the masses doesn't care in any way how they appear in public, then that's just a problem that will likely never go away. I suppose as long as people are willing to accept the abuse then it won't negatively affect the project that much in terms of contributions.

Another one, got it. As long as people still continue to desire to contribute then other people's behavior is totally acceptable.

So far, I have yet to see any one person's comment reach the level of the quoted statement. If you can't see that then I guess we'll have to agree to disagree. Also, you are assuming quite a lot about my level of tolerance for political correctness. Simply pointing out that someone behaves in a bad manner and suggest that maybe there was a better way is not political correctness.

Again, we shall have to agree to disagree. Projects will carry on regardless.
