I wouldn't say ridiculous. Terrible? Sure. A tragedy? Certainly.
White supremacy is founded upon the idea that the straight white male is superior to any other demographic in the world. Centuries of forging the global empire in the name of God (Manifest Destiny) and a sense of messianism (White man's burden) has caused the eugenicists to end up on top, through fear mongering.
Bayer has openly admitted to selling HIV-positive "medication" to Latin American and Asian countries. There is a reason why HIV is most common among demographics despised by the straight white male. In fact, during WWII (During which the straight white male supported the Nazis 100% btw), the German chemist who was going to be sentenced for war crimes in Nuremburg fled to the United States, where he was made the Chairman of Bayer.
By withholding essential services such as harm reduction, contraception, and safer sex education from certain demographics, white supremacists allowed HIV to be prevalent, in hopes that it would exterminate the people they didn't like. Hitler was influenced heavily by California-style eugenics.
Oh yeah, there is a genocide being orchestrated against Aryan populated nations, but it is "white supremacy" which is trying to destroy other demographic in the world.
You like the poster you quote have a problem. The first one is white genocidist. Undeniable. The truth he want to still what he couldn't build in homeland.
Now you are a sick loser by using the term aryan. This is a lie. You will by doing so exclude Russians. What is your problem. The white genocide is real, worldwide and systemic. They (who ever they are) hate us. Don't get weak by using the narrative of a defeated ideology.
