Given the number of responses to my post, this post is my 'reply to'...
First, the "major premise behind such laws" is to require a "compelling State interest" when a right to exercise religion is prohibited. That is as true of the federal RFRA (supported by Clinton, Schumer, Kennedy, etc.) as it is of Indiana's new law. If anyone believes (pro or con) that it is going to materially affect gay marriage or access to store purchases they are mistaken.
Second, "why is it needed on the state level"? It is needed to clarify Indiana's minimal and ambiguous case law. There are 31 states with RFRA protections, 20 of them due to their specific RFRA legislation and 11 others due to their Constitutional and/or clear case law. The value of such laws are in their application to a wide variety of judicial disputes such as (in other states) the privacy of financial records, state taxes on businesses run for charitable purposes, the limits of State entanglements in contracts between individuals requiring religious procedures, and dozens of others (see case law examples in this summary:
https://inadvancesheet.files.wordpress.com/2015/03/rfra-state-by-state-listing.pdf). Such laws help define cases experienced elsewhere, such as whether or not you have a religious exemption if you feel obliged to help someone commit suicide, or a religious exemption to not testify against your partner, parent, or child.
Third, contrary to one comment, I know I live among "many" gay people, one of them being one of two closest friends (in the Bay Area). And contrary to that poster's image, I have other social associates that are gay and i have enjoyed attending their hosted social parties and celebrations (their Solstice Party being an annual ritual). And I no more want to "punish" my freind or gay associates for partnering than I do anyone who is straight. And I completely emphasized with those happy gays couples that waltzed out of the civil marriage office (my property title research cubicle was 10 ft from the marriage license-cermony section).
None the less, it is not an "the absurd notion that gays are desperate for the social 'approval' of homophobes, as if we respect and crave the moral judgments of the wickedly deluded". Given the gay movements recent public face, that of a hysterical social and moral mania, with many well-known personas openly gushing their enjoyment for joining a righteous, absolutely certain, and hateful movement - well, that begs for an explanation, does it not? (It certainly isn't based on substantive discrimination in public accommodations).
One such explanation of the irrationality is also true of any vocal and angry identity based minority, their collective subconscious understands that they will never be "normal", no more than any unusual fetish is thought of as "normal". One way to do deal with it is to accept it and move on. Another way is to expect others to constantly reassure them that they are NOT surrounded by homophobes and reassure that they are normal and equal - it is a reality that can never be attained and a need that can never be satisfied. Blacks will never be quite the same as whites, women the same as men, and gays the fully same as straights. Hence these grievances will never end; rest assured, in the year 2115 there will still be unimagined mico-carping whines, which to our contemporary ears would sound laughable.
Four, someone stated: "I believe people pick up prejudices innocently, but some grow to adulthood not only never questioning the prejudice, but actually using their intellectual capacity to make up reasons to keep hating and belittling people. Maxparrish has no idea how his shallow, infantile, and simplistic assessments of others' motivations reveal his own methods of thinking."
But might it be that hate and belittling a social mania of value to that someone and it is his REAL gripe? I do not hate gays, but I do hate irrational mob mentalities, needless bullying, and widespread social hysteria due to ignorance. Be it the fury over Terry Schiavo or the fury over Eich or Indiana's RFRA - such folks who participate are a part of idiot mobs.
Last, someone mentioned "I thought this was just about gays wanting to be able to get married... and served at stores. If gays were trying so hard to be "normal", they'd be flocking to Bachmann's Degayanater Service in order to become normal. Instead, they've accepted who they are, and the US Constitution says everyone else must as well." If this is truly about gays getting married and getting store service, then how do you explain the benighted stupidity that is behind "dinner-bell" panic and rage?
Nope, that explanation won't do.
