White males are, by being white males, in two protected classes under the 14th Amendment as well as virtually all domains with statutory anti-discrimination laws.
Heck, the cass that established gender as a protected characteristic under the 14th Amendment, subject to intermediate scrutiny rather than merely the rational basis test that is the minimum for any legal distinction, was brought by male plaintiffs against a state law placing higher minimum age limits for men in a law controlling alcohol purchases. Craig v. Boren, 429 U.S. 190 (1976).
