Wow, I think that was the first really potent flamewar we've had on llvmdev. Looking on the positive side, I think this shows that the llvm community is growing and drawing interest from new people with new perspectives. This is a good thing.
I want to thank everyone who was courteous in their response. As others have said, it is really important to be polite and try to be understanding, particularly on widely read mailing lists. Sometimes it is hard to understand what someone means or what perspective they are coming from. I don't think the occasional flamewar is disasterous to the community, but we want to encourage a helpful and friendly atmosphere.
Finally, we want to encourage people to speak up if they have a question or a problem. llvmdev currently has 637 subscribers, and probably a large number more that read through gmane and other aggregation services. If you have a question, feel free to ask. When asking about something, phrasing it positively is good, as is sticking to specific technical questions. Being argumentative is not generally useful, particularly if you are new to the community.
