No, browns don't need to be genocided because of their inferiority. If they'd need to be it's because of the suffering that they create.
The difference between animals and browns is that browns destroy and create suffering.
They don't need to be eradicated completely, but it would be objectively better for all life if their numbers were greatly reduced and they were never given industrialized technology. It is not even close to anything Whites have done. If you are a White person and have travelled to india, varanasi (one of the most holy areas for exaple) you can see the extent of their destruction.
Much of the suffering in their places are directly caused by browns. And much of it is done by higher class browns purposely want slaves and are inherently psychopathic. And not just a small minority, but basically any brown that enjoys having a scourge as a servant.
I don't think current Whites are the final form of a supremem being. What differs us in our approach is empathy, jews don't have it. We've only allowed ourselves to be destroyed so much in such a way because of it. No other group would have gotten to our point based on the same lies.
And specficially again, it's suffering that they create. Thay's the difference between Whites and jews and browns. Jews want suffering, browns implicitly create it. Whites do occasioanlly, but we make sacrifices to try and reduce it. And never, never, not even close to the leves of what goes on in brown countries. Sorry, really not even comparable in magnitude, prevelance and intensity. Likewise many, many are completely apathetic and believe that what their doing is atleast partly natural.
If browns were ever given any seat of power, the entire world would be a hell.
There should be less power overall, no power for jews, and very very little power for browns. They cannot exist in industrialized societies, it's cruel for everyone--themselves the most.
