how bout this.
christians love God. they are taught to love God more than anything. if you commit a sin, you hurt God, cos the bible says that he loves you, and when you betray him by breaking his rules, it hurts him. so do you think that a christian who has a strong faith and love for god, is going to want to have anything to do with a gay wedding?
But they're not getting married to same love people themself, they're just giving food to people attending one.
You could argue their still associating with sinners, and you'd be right in that case.
But everyone sins. You can't not sin, because many things you do frequently, and even some of the most basic of human emotions are sins. So everyone they associate with is a sinner. But for some reason, homoloveuality is the only sin they can't associate with? It's just more picking and choosing
