If you are shopping in Hobby Lobby for a product or service they don’t provide, they are not required to provide it. You cannot legally force Hobby Lobby to perform homosexual “marriages.”
Nothing in my post said either of these things. But the Knapps advertised The Hitching Post in a manner that made absolutely no reference to specific religious beliefs or prohibitions of any sort; only that the marriage ceremonies are performed by ordained and licensed ministers. They do not advertise “opposite-sex marriages only” or prohibit any legal unions. Here is the ad:

It seems to me to be a “come one, come all” solicitation, very much like any business open to the “public” and unlike a private club or other organization with membership requirements. I wish the Knapps well, but I think they will lose this one. My preferred solution, which I have advocated many times on FR, is to get the government completely out of the marriage business.
