WASHINGTON — The Confederate battle flag should not be displayed on the South Carolina capitol grounds or as part of any state flag, 29 LGBT groups across the country said Tuesday.

"We support efforts to remove the Confederate flag as a contemporary symbol in the public square, beginning in South Carolina," the groups, including the Human Rights Campaign and several national legal LGBT groups, said in a letter provided to BuzzFeed News. Among the state groups signing on to the statement were three South Carolina groups: ACLU of South Carolina, SC Equality, and South Carolina Black Pride.

The groups joined a chorus of calls for the removal of the flag from the South Carolina statehouse grounds in the wake of last week's shooting deaths of nine black people in Charleston, South Carolina's Emanuel African Methodist Episcopal Church on June 17.

Going further than many statements this week, the groups also said the Confederate battle flag and "versions of the same ... should not be flown in a place of honor as a part of any state flag" — a call that would implicate Georgia and Mississippi's flags, as well as potentially other states' flags as well.

The groups go on to state that they "also recognize that our work isn't done with the state's disavowal of a racist symbol." Specifically, they state, "[W]e also stand committed to addressing the hard truths that divide us, to finding solutions for the inequities facing people of color, and to ensuring access to fairness and to justice for all."
