But they're not banning Zionist (Jewish nationalist) content, only White natl content. So they're engaging in illegal discrimination due to disparate impact.
True.

Disparate impact discrimination is illegal under Title VII (employment) but not Title II (public accommodation), so even assuming FB is covered by Title II (which is dubious), and even assuming this would be found to be disparate impact discrimination (which is difficult to assess because the test for that is narrowly tailored to Title VII context), it would not be illegal on that basis.
