Where certain “fundamental rights” are involved, the Court has held that regulation limiting these rights may be justified only by a “compelling state interest,” Kramer v. Union Free School District, 395 U.S. 621, 627 (1969); Shapiro v. Thompson, 394 U.S. 618, 634 (1969), Sherbert v. Verner, 374 U.S. 398, 406 (1963), and that legislative enactments must be narrowly drawn to express only the legitimate state interests at stake. Griswold v. Connecticut, 381 U.S., at 485; Aptheker v. Secretary of State, 378 U.S. 500, 508 (1964); Cantwell v. Connecticut, 310 U.S. 296, 307-308 (1940); see [410 U.S. 113, 156] Eisenstadt v. Baird, 405 U.S., at 460, 463-464 (WHITE, J., concurring in result)…. MR. JUSTICE STEWART, concurring.
