Evidence

Similar to the experiences of Jews, suburbanization became a vehicle for Catholic cultural assimilation into Anglo-American normalcy.

Aziz, The Racial Muslim, 455

• XREF: Connects to the broader scholarship on the social construction of Whiteness (e.g., Noel Ignatiev, David Roediger) and 20th-century redlining politics.
• SEED: Angle: how the absence of discrimination against a group in housing law operated as a de facto admission ticket to Whiteness — a measurable, material proxy.
