Over here churches were raided or destroyed during WW2. This probably made us more ignorant to what is “holy” and should not be touched upon.
I respect your beliefs, but the “damage” is irreversible. This map exists for more than 3 years now and is spread out all over the world. As most know, it’s impossible to wipe something from the Internet by force, you can only try to get something forgotten about. (For as far that would be possible.)
My advice: show your depreciation as Ifurita said by leaving the server which runs it, say no to any competition playing it, or what means you deem necessary to make it clear that you think this map should not be played for religious means.
However, I would hold back in any way to start more commotion about it as nobody would benefit from this.
