An emergency room physician or EMT could refuse service to a gay person in need of immediate treatment.
???
What strongly held belief could possibly justify refusing to help people. especially someone who could die? People are free to believe that others are going to Hell, but that does not give them the right to deny service. Saving the life of a gay person does not make one complicit in homosexuality.
I have a little more respect for the idea of being unwilling to dispense medications that are against their religious principles. In such a case a religious person may feel complicit———so then they should not go into pharmacy! People with unusually strong beliefs have always had to make sacrifices to maintain their religious scruples; it is wrong to expect everyone else in society to sacrifice their rights to accommodate them.
So, when pacifists withhold the proportion of taxes that go to the pentagon, will their religious beliefs be honored? This is madness.
