Why in the world would anyone who claims to be a Christian support a church that would let Gretchen Graf be a "minister"?
A lot of folks are asking the same question of the PCUSA, ECUSA, ELCA, UCC, and UMC. Why the Pewsitters continue sending money to support these denominational monsters is beyond comprehension.
What is typically happening is the Pewsitters are wondering why the membership in the mainline protestant churches continues to drop. Instead of reading the available information about the heretical actions of their leadership, they instead wring their hands and believe their minister when she states that "all mainline churches" are in decline so there is nothing one can do about it but send more money to the denomination.
