It actually translates as 'Hail Victory' but the point is its associations in the past and, in some contexts, the present. It's a criminal offence to use it in Germany, Austria and Switzerland for starters and all it takes is for one very annoyed German to complain and all hell will break loose... Additionally, it's the thin end of the wedge... if it becomes acceptable then the lines become very blurred and troubled... look at the terminology applied to some ethnicities where some are 'owning' a particular word which now causes all sorts of trouble because some people seeing it being used see it as being acceptable when there are still many people out there who find it objectionable and distressing... it's all about context and about sensitivity; remember that... People do still get offended by these terms and there are very good reasons for that being the case....
I can only half agree with your post.
This is a difficult thing. On the one side i fully understand people feeling annoyed in real life.
In this specific "Siege Crusaders" context they just do some good role playing. If people feel annoyed by a small group trying to add player generated content i can only shake my head.
We simply don't live in the past anymore. What happened in the past had happened and cannot be reversed, unfortunately.
But referring to a behaviour coming from a game and taking it personally and projecting it into the real life is what i don't understand and maybe i never will.
However, you've made a fair point but i have a different opinion about it.
Hail the emperor. Never surrender !
