Can the bereaved family request that a man in a dress fade into the background at their funeral memorial event? They are the ones paying the bill and they are the ones with the religious ceremony that the funeral home is providing.
The problem is more that families planning a funeral meet and deal with the director handling the funeral numerous times. There is no fading in the background then.
This also means that Catholic schools will no longer be able to terminate the employment of a teacher who declares they are in a same sex marriage or who decides they are the opposite sex and dresses so. It means that schools must allow students who declare they are the opposite sex full unencumbered access to all facilities and activities of that sex. So no more banning boys from the girl’s locker room or track team. It means a business’ health insurance policy must cover hormone treatments for transgenders and very likely surgery to change sex. It probably means that driver licenses must now be issued according to gender identity and not biological sex (even if there has been no actual sex change). In short a total disaster for religious, personal, and economic freedom.
