You actually reflected my own feelings. There people are less respectful towards others genuine problems and tend to make fun of it. I experienced it just yesterday. The same experience in Linux and UNIX users and superuser. Ask Ubuntu has always been safe bet for me.
Also you are right about cross cultural integration. The words one culture may speak easily can be viewed as offensive in another culture (although I doubt turkey is a cool word in any culture)
Once I challenged a user in Linux and UNIX users that Linux is not an operating system. Only kernels are operating systems. And I gave lots of research links. The user quickly wrote me off as a troll. So much unfriendly type of users over there.
In that sense askubuntu is a great site, much better than other SE sites.
