This week, more than 2,000 signatories — members of Congress, women’s rights groups, businesses — submitted nearly 50 friend-of-the-court briefs to the Supreme Court in three pending cases involving L.G.B.T.Q. rights.

The cases, which the court is likely to take up next session, consider whether Title VII of the Civil Rights Act of 1964, which prohibits employment discrimination based on sex, prohibits discrimination against L.G.B.T.Q. people. The signers reflect what a broad cross section of Americans overwhelmingly believe: Such discrimination is wrong.

Polls consistently show a high percentage of Americans think that firing people or denying them jobs or promotions because they are L.G.B.T.Q. is wrong and that it should be prohibited under our nation’s civil rights laws. A full 92 percent said so in an April poll by Quinnipiac University. That’s in part because basic protections against job discrimination are fundamental to core American values of fairness.
