i noticed you said you're well-educated on Nazi dogwhistles. okay. cool.
i'm gonna be that one annoying guy and ask if you would mind making a post educating people on them & maybe making a list of possible ones, because not even i can fully spot whenever something is a dogwhistle (even a Nazi one...). if you're not up to it, that's just fine by the way.
A lot of it boils down to experience. Knowing what rhetoric is Nazi or pro-WP/white supremacy. Knowing what symbols or words they use to distinguish themselves. Literally being woke.
My favorite image of all time for this is this one:
I have found a source for most of them except the half-Chaos star. Literally zero info about it. But all others are very good signs grounded in history.
Dogwhistling includes altering these symbols to "hide" them, like the usual suspect Azov brigade:
Azov LOVES the Wolfsangel (a lot of Ukrainian Nazi batallions do too). You can even see the Black Sun in the background!
But lest I get called a pro-Russian shill, here's a symbol that is very frequently used by Russian Nazis or otherwise nationalists (most notably Rusisch):
That is a kolovrat, falsely attributed to be a Slavic pagan symbol. It's not. This is an 8-pointed Swastika frequently used by Slavic Nazis, mostly Russians.
I will note that this is mostly a symbol used by Russian nationalists than Nazis (there is a difference, as modern neonazis are rarely nationalist and moreso pro-White race supremacy), it's enough to make someone vary.
Anyone using "pagan" symbols in general can be pretty suspicious, especially when it comes to Nordic paganism and Celtic symbols. A lot of Nordic pagans are neonazis. Not all of them (we are a Nordic pagan ourself and a follower of Odin and Thor), but a lot of them. Hell, heathens even have a whole list of Nordic "pagans" to avoid on Google Docs.
Winged othala is an immediate giveaway it's a Nazi. Tyr/Tiwaz symbol also can be. Far from all Nordic pagans are neoNazis and you should never be prejudiced. Just pay attention.
There is also a page on Wikipedia about recognized hate symbols: https://en.wikipedia.org/wiki/List_of_symbols_designated_by_the_Anti-Defamation_League_as_hate_symbols
Sometimes they can be pretty covert, like putting "⚡ 100% ⚡" and claiming it's just some stylish battery life type thing. It's not. ⚡⚡ is code for SS and 100% is "100% pure white".
Modern neoNazis LOVE their White Replacement theory: they will complain that the white race is going extinct, how there is only 9% of white people left in the world, how these evil brown people are replacing them and marrying their wives and having mixed children.
They will frequently blame immigration for the replacement, and generally be extremely racist. This includes hating Islam on sight (don't let "but women rights" fool you, they only hate it because it's the brown people religion), having choice words for immigration, Romani and Indian people (as does most of Europe because they're fucking racist), and any stupid excuse they can use to excuse saying "this brown people is bad".
"Asiatic barbaric hordes" (common in anti-Russian sentiment) is just plain racism too, writing out Russians out of white people to be able to discredit them, thus implying that white people are somehow superior. White supremacy plain as day.
Nazis will often complain about crime rates. In fact if someone ever brings up the crime rates it's a Nazi. On sight. It's always mislead, misinterpreted statistics that ignores conditions like poverty (common with immigration done by capitalists importing cheap underpaid labor) to home in on someone's race.
A very common one Nazis have is putting things into triple parenthesis, like (((this))). The ((())) is used by neoNazis to mean that whatever is encased in those parenthesis is (secretly) controlled by Jews.
Don't be mistaken: Nazis don't always hate Israel. Some of them LOVE Israel, because it proves their wet dreams about Jewish power secretly controlling the world. They are united in their antisemitism.
Anyone who talks bad about USSR pre-Khrushchev (Lenin/Stalin era) will inevitably accidentally state/imply something among the lines of "Nazi Germany should've won" or otherwise state/imply that between USSR and NG, NG is better in some way. This is just white supremacists coping.
Double genocide theory/Holodomor is a Nazi theory perpetuated by liberals in an attempt to discredit USSR. And I will really insist on this: because saying that USSR killed more or just as much people than Nazi Germany is NAZI APOLOGIA. Saying "I don't understand why Nazis are hated but USSR/communism isn't even though they killed similar amount of people" IS NAZI APOLOGIA.
How? Because if this was true, communism would be hated. This is just fake woke shit used to deny and lessen Nazi crimes. Do not let them erase Nazi victims for a bullshit lie.
There is probably more, but I got to go since I've got a Christmas party to attend to. I think I've put as much as I could.
