She's being persecuted for opting out of creating art that celebrates and event she considers a sacrilegious desecration of a sacrament.
She didn't discriminate against anybody, she didn't toss anyone out of her shop. She didn't say "You can't buy flowers and take them to your event." She just said "I will not create special art for an event I object to on a religious basis."
She doesn't have to. And the left naturally will crucify her for it. You guys are good at crucifixion.
Her flowers are not integral to the event. They are not part of any sacrament, ritual, rite or worship. They are decorative, that's all.
She cannot hide behind her faith to rationalize her bad behavior. She is adopting the same tactics as the Taliban when she perverts her faith to discriminate.
