Marianne Duddy-Burke, executive director of Dignity USA, an LGBT Catholic organization, said it's important to note the distinction between Catholic leaders and parishioners.

"The funding that's from the official church — that is being spent by the bishops who are not accountable to parishioners, many of whom are absolutely furious and appalled at the fact that their bishops are spending the money that these folks donate to help support their parishes [and] folks really who are underprivileged and who should be at the core of our concerns," she said. "To have that money be directed to campaigns to legitimize state-sponsored discrimination is something that most Catholics, when they're made aware of it, find infuriating."
