"Will it force businesses"
One word: Pepsico.
Can you say 'Ferengi', Mike Fuckabee? (emphasis added):
'The Ferengi do not appear to appreciate class or have a class system. Even though their status is determined entirely by wealth, the Ferengi would consider it foolish to establish an "upmarket" clientele when there would be profit to be made in selling goods to less fortunate people. In fact, the Ferengi belief in the "Great Material Continuum", an analogue of the unrestricted free market, often drives them to great length to satisfy a potential customer's needs and to find a market for their goods.'
I know you can. Shareholders do. Even the most right-wing socially conservative investors will become hyper-tolerant liberals when they can see a potential profit stream from one section of the population. The 'Pink Pound/Dollar/Euro/(*insert currency of your choice here*)'. It would be financial suicide to alienate that; LGBT people can always vote with their wallets.
'Racism is almost unknown among the Ferengi. It is unclear if there even are racial divisions among the Ferengi. Indeed, believing that a Ferengi merchant would refuse to serve anyone because of their race is almost unthinkablethere would be no profit in it.'
Racism. Homophobia. Nope, not seeing any difference there, Mr. Fuckabee.
'Pink Dollars'. Straight Dollars. To the shareholder they're the same thing.
The same can be said of people.
Quark (Armin Shimerman): 'I think I figured out why humans don't like Ferengi'
Sisko (Avery Brooks): 'Not now, Quark.'
Quark: 'The way I see it, humans used to be a lot like Ferengi: greedy, acquisitive, interested only in profit. We're a constant reminder of a part of your past you'd like to forget.'
Sisko: 'Quark, we don't have time for this.'
Quark: 'You're overlooking something, Commander.
