I don't think we're judgemental enough.
Windows XP isn't a Sever OS. We have never supported using Windows XP as a server, we routinely close questions that use Windows XP as a server for this reason - it really isn't relevant to professional system administration.
In hethe past we have supported people who deployed/managed XP in their environment, though we have never supported end users. Windows XP is past it's end of life, we will likely start to be less supportive of people still managing it and will almost certainly stop supporting people trying to deploy it.
Part of being professional is using the right tools for the job and managing the lifecycle of those tools. The question you link to demonstrates a failure to do both.
All in all I think closing the question as not being relevant to professional system administration was a good call.
