The DM was a DM asking us to change our no tankies policy and remove the fuck tankies banner as it was apparently upsetting hexbear users. Apparently tankies view the word tankie as a form of slur. The admin wants us to ally as a form of "left solidarity"
The post was very clearly saying that Ghengis Khan and the post-Mongolian Chinese state is a worse form of conquest and murder because they were conquering and killing their own people.
But the US was killing Native Americans which weren't citizens, so it is not as bad as killing your own people like the Mongolian/Chinese/Mao.
Uh, ghengis Khan certainly killed a lot of non mongols. He pretty strongly justified the conquest on such terms. (that, and loyalty/fealty). Many leaders through time did.
All that said, consider football. A point is a point, but an own goal stings worse. Not because the opposing players are subhuman, but you were supposed to do best by your own.
