This game is not, in all aspects, politically correct. In fact it supports a several silly stereotypes, and it surely contains several aspects which are historically completely incorrect. There is no doubt about it. I'm also convinced that none of these incorrect representations were or are intended and that people who contributed to the core data of this game did not intend to insult anybody. However, I'm not convinced that any changes should take place to make this game more in line with history, unless its developers can be convinced that any one of these misrepresentations that it causes anyone real harm and that the possibly serious efforts involved in making any suggested changes happen will be worth it.
A name change is, admittedly, a minor change, but it will most likely not happen for the 3.5.0 release. If constructive suggestions are made and good names can be found it may be possible to make such changes during or after the merge of MG + GAE.
