Of course TheMeInTeam is defending the reclamation of a Nazi symbol by invoking whataboutism. Lexicus specified "from the Nazis", you know? They didn't specify "from a random unrelated group that don't use it as a hate symbol".
Also, notably, it hasn't universally been branded a hate symbol. It has, in specific countries given specific context, been labelled so.
Here's a handy link, from an incredibly safe source (last paragraph on the page, no internal anchor tags, sorry). In day-to-day conversations, it's normally easy enough to work out if someone meant the pre-Nazi Indo-European symbol for good fortune, because it's usually immediately apparent from context.
On the Internet? Comparatively harder. But that doesn't mean we shouldn't trend to believing in the benefit of the doubt, because a) a lot of games shy away from historical re-enactments of factions in World War II, and b) it completely removes the possible context of it
not being Nazi in origin, because it's basically inapplicable to any strategy game in its original form (outside of some vague lore or aesthetic theming for a particular minor faction, I guess).
It also gives cover to these invocations
as dogwhistles. If you're opposed to letting the alt right, or any similar grouping, win in their use of these phrases, you shouldn't be giving
anyone the benefit of the doubt. You should be happily joining in in exposing such attempts at wordplay. I mean, you almost had it. If something is no longer a dogwhistle, then yes, everyone knows exactly what someone means when they say it. This is good, because it removes that benefit of the doubt. You are then emphatically sure that that person is, or isn't, a neo-Nazi (or someone similarly aligned to that cause). Is it a shame that that language is then lost, in the modern context? As someone with a great interest in language and etymology, absolutely. But it'd be more of a shame if hate groups could continue to use it, while masking their efforts under the guise of normalcy. That twisting of the language is on them - they chose to do it, to cover their hate. It's not anyone elses' fault.
