It means the Roman Catholic Church wouldn't want to hire a known gay person to run one of their soup kitchens or other charities.
But where does it say that this bill applies only to gay people? I find it hard to visualize a business hiring a homeless person to represent them. What would disqualify a homeless derelict? Sure the homeless person can be a good person but i dont know, like a five star hotel having a bag lady behind their desk. Is this even realistic? Or not even a homless person , suppose i want to work dressed in a plastic bag?
