It appears there may be problems within the Veteran's Council though. The screen capture below is from the Facebook page of a group that has withdrawn from the council.
Two years ago, history was made in Boston when OutVets, an organization composed of Gay veterans, was invited to march in the 2015 St. Patrick's Day parade put on by the South Boston Allied War Veterans Council.
That invitation came after a lawsuit was filed 25 years ago by a gay veterans group who were denied the right to march in the 115 year old parade. The lawsuit made it all the way to the Supreme Court which determined the parade organizers had the right to decide who marched in their parade.
But organizers had a change of heart in 2015 and OutVets was allowed to be part of the parade. They were invited again in 2016. But this year OutVets was denied participation in the parade.
The reason given for the ban is because the group's logo contains a rainbow which the committee felt is too associated with Gayness. They determined this somehow violated one of their rules. The rule specifically applies to "sexual orientation" which is a politically correct way to avoid coming out and saying Gay.
If you look at the rule below it's hard to see how a rainbow logo could be misconstrued to be a theme of a St. Patrick's day parade.
