Because we reject the notion that the mere "equal application" of a statute containing racial classifications is enough to remove the classifications from the Fourteenth Amendment's proscription of all invidious racial discriminations, we do not accept the State's contention that these statutes should be upheld if there is any possible basis for concluding that they serve a rational purpose. The mere fact of equal application does not mean that our analysis of these statutes should follow the approach we have taken in cases involving no racial discrimination where the Equal Protection Clause has been arrayed against a statute discriminating between the kinds of advertising which may be displayed on trucks in New York City, Railway Express Agency, Inc. v. New York, 336 U.S. 106 (1949), or an exemption in Ohio's ad valorem tax for merchandise owned by a nonresident in a storage warehouse, Allied Stores of Ohio, [388 U.S. 1, 9] Inc. v. Bowers, 358 U.S. 522 (1959). In these cases, involving distinctions not drawn according to race, the Court has merely asked whether there is any rational foundation for the discriminations, and has deferred to the wisdom of the state legislatures. In the case at bar, however, we deal with statutes containing racial classifications, and the fact of equal application does not immunize the statute from the very heavy burden of justification which the Fourteenth Amendment has traditionally required of state statutes drawn according to race.
