What's wrong with exogamous marriages? Moses had an Ethiopian wife, and his critic was struck with leprosy (Numbers 13). Is that the "Jєωιѕн" "race mixing" your talking about?
You're either naïve in the extreme, or you're being flatly disingenuous if you mean to imply the Jews have not made a huge, culturally ubiquitous effort at eliminating "whiteness" by every means at their disposal - flooding white countries with foreigners, spreading dekulakization narratives vilifying whites for their "privilege," and, yes pushing images of mixed race couples on TV, in films, and advertising. Jews associate "whiteness" with Christendom, and are not satisfied with even a 100% apostate Europe and America. They want to wipe out the sons and daughters of Christendom completely, as they see us as Edom - their ancient religious and ethnic enemy.
God bless you if you've lived a life so blessedly sheltered that you haven't noticed, but Jews do promote race-mixing, despite your scoffing use of scare quotes and Poche-level scriptural cherry-picking.
