Why don’t whites create their own media sources?
They do - Nick Fuentes created one and he is viciously censored, deplatformed, smeared, and accused of virtually everything under the sun by a network of seething jews.
Why don’t white create their own banks?
Hitler tried this, eventually someone will try again and hopefully this time it sticks.
Why don’t whites literally just run for office?
They do, if they don't support jewish interests, the jewish media will smear them, the jewish donors will fund his opponents, and the jewish NGOs will get their supporters removed from social media
If none of these options are working, what do you suppose Whites are left with? How long do you think they'll allow this to continue before they start firing up the cattle cars?
