The Django trademark is for a specific context-- downloadable CMS software. You are free to use Django in other contexts, such as naming a car, a band, or whatever.
But my main point is that, while I understand that the Django Software Foundation has a trademark on the name Django in a specific content, it ought not to be possible to trademark a common name at all.
If Roberts and Sons Cleaners is an established brand in a community, we would want a legal mechanism for that business to protect their brand - without having to change every business name to XYZZY, etc.
So I think businesses can get trademarks for English words and common names - with the understanding that they might be geographically or market-segment limited in their protection.
