The more I think about this, the more I don't understand the family here.
They could have held the funeral at a church of any of the following denominations and had no issues with the church and the fact that the deceased was a lesbian woman:
Church of Christ
Metropolitan Community Church
Disciples of Christ
Community of Christ
Many mainline protestant churches. Even most Methodist Churches. They could have went to any of those denominations and any of those Churches would have been completely accepting of their daughter and her family. So why on earth did they go the house of bigots to have her funeral? Would you let the Klan conduct a funeral for a black man. It just seems like a slap in the face to this deceased woman to hold her funeral at an anti-gay church.
