The bishop of Springtown will not, will not be moved:

As reported at Catholic Culture, the bishop made it clear that anyone attempting to enter the cathedral wearing the “rainbow sash” would be denied entrance, and anyone praying out loud for same-sex marriage would be asked to leave.

“It is blasphemy to show disrespect or irreverence to God or to something holy…Since Jesus clearly taught that marriage as created by God is a sacred institution between a man and a woman (see Matthew 19:4-6 and Mark 10:6-9), praying for same-sex marriage should be seen as blasphemous and as such will not be permitted in the cathedral.”

This is really common sense when you get down to it. Using worship space to pressure whom? God? A bishop? None of these. Voters!
