[Well, that's not a fair comment. First of all, you hide like a scoundrel behind the nature nurture thing with the tired old dead horse "well, gays don't have to be gays, maybe." Even if that had any scientific validity, and it does not because it's immaterial as to why an individual enjoys greater sexuality with a same sex partner, it would still be tripe. The muslim baker may not approve of alcohol, but he's baking cakes for couples with champagne toasts or he's gonna go out of biz and broke. That, is you're elevating one "sin" over another. And, your sin is irrelevant to me, anyway.
Second, there is no first amend SPEECH consideration in commerce beyond advertising. The baker has a first amendment contract right. However, the sup ct has said that right does not extend to overrule a law forcing one in commerce to offer public accommodation to all. If you want to relitigate civil rights ... good luck cause you're gonna lose. Roberts ain't going there. Furthermore, the mulsim baker has a choice. He can simply pay the fine or whatever and not bake the cake. He's not going to forced to convert under torture.
Lastly, this is simply too crazy to bother with, sorry.
It would force the gay couple back on their heel to prove that their behavior was an innate state of being and not picked up along the way; like so many gay men for example present with a clear history of same-gendered child sexual abuse/imprinting.
It doesn't fcking matter how somebody turned out gay, or why some white woman fell in love with a black man. It happens in nature.
You leave the baker alone to his 1st Amendment rights and if he wants to go out of business by lack of patronage, then that's his affair. Otherwise you don't have a secular behavior forcing a religious one to bow down to him and abandon his first amendment rights as a matter of law.
Well, that's all fine and dandy, except for the fact that whether you like it or not, the state has the power to tell the baker to serve everyone or face a penalty.
Perhaps more importantly, I think you're mixing and matching "rights' to serve your own predetermined equities. The First means the govt can't have a state religion. But, Indians did not have a right to use peyote in religious ceremonies. Similarly, I may believe that God did not intend for whites and blacks to eat together, and I have no legal duty to sell my fried chicken to blacks. Simply put, if there is a really good reason your exercise of your religion is harmful to society, you're exercise of religion may be limited. There's nothing new, or remotely controversial in this. We do, from time to time, reconsider whether native americans smoking peyote, or Mormons marrying more than one wife at a time, really negatively affect society. Though why anyone would smoke something that can lead to puking, or having more than one nagging ball and chain at a time, is beyond me.
simply put, by mixing and matching rights, you seek to elevate your distaste for homosexuality above another's desire to be with a same sex partner, and in doing so you cry victim, when in fact you're no more or less a victim that the gay person. If a person wants a sexual relationship with another person, and doing so is detrimental to society, it can be proscribed. Similarly, if your behavior in exercising your contract rights acts in a way that's detrimental to society, and you don't have a really good reason to do so, you can be fined for not baking the cake.
