In the same vein, redlining wasn't targeting racial minorities per se, it was just targeting things that correlated with it highly. Under current civil rights legislation that is still highly illegal;
gender-ish policy is still an explicit policy considering gendered things.
> "A recipient’s express or admitted use of a classification based on race, color, or national origin establishes intent without regard to the decision-makers’ animus or ultimate objective. Such classifications demonstrate a discriminatory purpose as a matter of law. See Miller v. Johnson, 515 U.S. 900, 904–05 (1995); see also Wittmer v. Peters, 904 F. Supp. 845, 849–50 (C.D. Ill. 1995), aff’d, 87 F.3d 916 (7th Cir. 1996). “Put another way, direct evidence of intent is ‘supplied by the policy itself.’” Hassan v. City of New York, 804 F.3d. 277, 295 (3d Cir. 2015) (quoting Massarsky v. Gen. Motors Corp., 706 F.2d 111, 128 (3d Cir.1983) (Sloviter, J., dissenting)).
Where a plaintiff demonstrates, or an agency determines, that a challenged policy overtly and expressly singles out a protected group for disparate treatment, “a plaintiff need not prove the malice or discriminatory animus of a defendant ….” Bangerter v. Orem City Corp., 46 F.3d 1491, 1501 (10th Cir. 1995); see also Ferrill v. Parker Grp., Inc., 168 F.3d 468, 473 n.7 (11th Cir. 1999) (“[I]ll will, enmity, or hostility are not prerequisites of intentional discrimination.”). Rather, the focus is on the “explicit terms of the discrimination,” Int’l Union, United Auto. Aerospace & Agric. Implement Workers of Am. v. Johnson Controls, Inc., 499 U.S. 187, 199 (1991); that is, how the recipient’s actions specifically deprived or otherwise adversely affected the individual or individuals of access to a federally funded program or benefit. Even benign motivations for racial classifications are presumptively invalid and trigger strict scrutiny in Equal Protection Clause and Title VI cases. Adarand, 515 U.S. at 223–24 (1995); Grutter, 539 U.S. at 326" [1]
