SemlerPDX has given us pretty clear instructions regarding the use of references to Hitler, SS, etc, Squad and player names included and its strictly out. I don't hesitate to resign squads who do that, and kick them if they persist or argue about it.
I wasn't around to hear the banter with Ranger but lets all be honest here, Ranger you don't exactly have a perfect record either mate. I've heard you abusing players in the game for not doing what you want them to do. Most of us use have used filthy language either in TS or within our squads especially when we are with players we know. BUT blatant racism is another thing, and should not be excused.
