Sometimes, I wonder how people with such ideas can lead "an almost normal life" and find so many others with similar crazy ideas.
At least in German internet forums, they are often writing their crazy ideas in such a very bad German - writing in absolutely correct "High German" is often really difficult (!) - so that many of them arouse easily the attention of the better educated Germans and then, they have to suffer from tough or funny returns or "back-strikes" from the more intelligent average Germans.
Because many of those conspiracy theorists are also right-wing-extremists or real neo-nazis, they sometimes use nazi-symbols for their "subculture" and many of their German opponents from the political left are using persiflages or mockery of their colors, flags or symbols to show how ridiculous they are for them.
In Germany, it has almost become a science of its own to find through all the use of symbols or their opposite use by the enemies of Nazis.
For example, what I found very funny was the use of this swastika parody by left "nazi-hunters" who called themselves "Hooligans against correct Sentence Structure" in internet forums:

It usually means:
"Great! Now you can be proud of yourself because you have finally managed to write one single sentence of your nazi-propaganda in correct "High German!" !
Concerning "proud": I have never seen before such silly combinations of (tattooed) nazi symbols like beneath the "storm troopers" which stormed the US Capitol last week.
Even the most famous Swiss newspaper "Neue Zürcher Zeitung" had an article about that and other newspapers wrote that much more countries should outlaw the use of such symbols like Germany or Israel did:
Wer sich die Bilder vom Sturm auf das Capitol genau anschaut, entdeckt in den Fahnen, Kleidern und Tattoos der Teilnehmer zahlreiche Symbole. Wer sie entziffert, begibt sich in ein Gruselkabinett von irren Ideologien.

But on the other hand, the extremists then find some almost forgotten old symbols from a completely different history in an opposite sense and use it for their own purposes.
There is one example which really makes me angry, because right-wing-extremists and neo-nazis are using during the last five years or so this flag as their symbol of "resistance" against our German state authorities or against the so-called "Merkel's Corona-dictatorship" etc.:

This is the "Wirmer-Flag", which was discussed as the new German flag after the fall of "Third Reich" between the German resistance fighters who tried to kill Hitler on 20th of July 1944. It has the German national colors in similarity to the cross flags of all European Nordic flags like the national flags Denmark, Sweden, Norway, Finland and Iceland.
After 1955 or so, it was almost completely forgotten because the German parliament chose the national flag like we know it today.
But this "Wirmer-Flag" is now suddenly used by German right-wing-extremists and neo-nazis as symbol of their "resistance" against our democracy and this is outrageous for me and certainly also for the heirs of the real resistance fighters against Hitler.
Anton Wirmer, the son of Josef Wirmer, who designed this flag, is truely horrified by the use of this flag by neo-nazis because they are representing everything against his father was fighting in 1944! :

And if you are interested in other symbols, which you could often see used by the crazy people who stormed the US Capitol last week, there are some more informations here below ...
(By the way, in Germany, according to the German legislation and in principle, the German police would have had to intervene before they were on the steps of the Capitol because their symbols on flags were outlawed and the police would have had to take their flags away and collect money fines right in that place.)
