It would be best if Congress repealed the "don't ask, don't tell" policy on gays in the military. But if it takes Tuesday's federal court injunction to end the discriminatory and damaging policy, so be it. The House voted in May to overturn the policy, but Senate Republicans filibustered a defense appropriations bill that included a provision repealing the ban. The Senate is expected to take up the measure again after the November elections. But if Congress doesn't act, the courts will.
