As everybody knows the Catholics recognize "saints". Early in the Protestant Reformation (mostly in England in this case) many Protestants got the idea that the belief in saints was a very bad idea so they went about RENAMING all the various religious buildings and streets named after Catholic saints.
While a windfall business for the sign painters guild it did nothing FOR anyone and the general public continued to refer to St. Mary's Cathedral as St. Mary's, and St. Gildas Pub as St. Gildas Pub.
Today hardly anyone remembers that battle over dead people had gone on. We call places whatever the owners want them called, and we name our streets as we please.
Using a saint's name on an address has no reflection on your own religious beliefs, nor should it. If you think it does that's a personal problem, not something of general concern.
It's the same here. If you don't like what Mormons do in their own religion, don't participate.
You can do what you want for Mormonism, but I will continue to fight Mormonism’s war against Christianity.
