The organizers of the St. Patrick’s Day Parade have voted to reject a LGBTQ veterans group from marching in this year’s parade, prompting swift condemnations from elected officials. Mayor Martin Walsh says he will not march in the parade if the group is again excluded.

OUTVETS, which includes lesbian, gay, bisexual, and transgender veterans, said in a Facebook post on Tuesday that it was denied a spot in this year’s event. The group had marched in the previous two years.

In a 9-4 vote, members of the South Boston Allied War Veterans Council, which runs the parade, denied OUTVETS entry into the 2017 parade. “The Council did not give a clear reason,” OUTVETS said in the Facebook statement, “but, given the tenor of the Council’s deliberations, one can assume it’s because we are LGBTQ. This is a sad day for the LGBTQ community and for veterans of all backgrounds.”

Walsh marched the past two years, after the council allowed the OUTVETS to participate.

On Wednesday, Walsh decried the parade organizers’ reversal. “I will not tolerate discrimination in our city of any form,” he said, “We are one Boston, which means we are a fully inclusive city. I will not be marching in the parade unless this is resolved. Anyone who values what our city stands for should do the same.”

State Sen. Linda Dorcena Forry, whose district includes South Boston, said in a statement: “I am deeply disappointed in the decision by the South Boston Allied War Veterans Council to exclude OUTVETS in the 2017 Saint Patrick’s Day Parade. For the last two years, I have had the honor of marching in an inclusive parade that has reflected the diversity of the brave men and women of our Armed Services. I ask the South Boston Allied War Veterans Council to return to the table, reverse their vote, and invite OUTVETS to participate in the parade.”
