There was plenty of racism in the New Deal, but obviously it still helped blacks for blacks to start voting Democratic in 1936.
Ding! Ding! Ding! Correct answer!
Criticizing the New Deal as racist because of the redlining it included is like criticizing the Emancipation Proclamation as racist because it didn't also include an active affirmative action Federal hiring program. Revolutionary for its time even if behind the times by modern standards.
Furthermore, redlining was a practice even before the 1930s. It particularly exploded in the post-war housing boom.
