It will also be a blow to the businesses. People will boycott those businesses they feel are discriminatory. There is plenty of precedent for this and often corporations have had to back down.

I once was involved with a city park that was created for the Boy Scouts but later turned over to the city. While I was there the Boy Scouts were banned from receiving financial aid from the city and people took a dim view of them when they used the park. The Girl Scouts, however, got a grant to use the park for weeks (This was the only city park in the country where there were cabins, bathrooms with showers, Fire pits, a climbing rock and a lot of other state park amenities). I think the Boy Scout acceptance of gays is a response to amend their discriminatory practices. But they still don't acknowledge of atheists, though.

It might come down to allowing discrimination but having to post any such discriminatory practices at the entrance to your establishment. That way anyone that didn't agree could simply boycott said premises.
