I'm not trying to dissuade the fact that Nazi insignia holds great tensions. What I'm trying to say is ...
<-- This, the KKK cross is permitted to be used in your regalia or profile. And obviously, the KKK is renowned for racial discrimination. So, when people see other people using it, and they (could) check our rules to see "Hmmm, racial slurs and discrimination is not allowed, but it doesn't say anything about nation or empire insignias." So they put it on their profile, or their objector, or chat bind.
Do you see how it could be confusing to players? Which is why the Nazi Swastika should be specifically stated in our rules or the rule should be absolved.
