Really, it would be funny if it weren't so sad. All of the SJWs are condemning the Indiana law, because they disapprove of the motivation behind it. However, it is nearly identical to the federal law that the SJWs applauded. The only differences are theoretical motivations behind the laws. The federal law was justified, in part, on the freedom of Native Americans to practice their religion. The Indiana law is justified, in part, on the right of businesses to refuse service when doing so would violate their religious beliefs.
The actual or hypothetical motivations behind the laws are, in the end, completely irrelevant. In practice, the law can be invoked by anyone who feels that their religious freedom is being curtailed. What's important is the content, so let's look at the laws:
The federal law, enthusiastically supported by SJWs, states: “Government may substantially burden a person’s exercise of religion only if it demonstrates that application of the burden to the person (1) is in furtherance of a compelling governmental interest; and (2) is the least restrictive means of furthering that compelling governmental interest.”
The Indiana law, vehemently condemned by SJWs, states: “A governmental entity may substantially burden a person’s exercise of religion only if the governmental entity demonstrates that application of the burden to the person: (1) is in furtherance of a compelling governmental interest; and (2) is the least restrictive means of furthering that compelling governmental interest.”
There is no significant difference between the two. What the SJWs are objecting to are the purported motivations of the people passing the law. In short: "it's good if we do it, but bad if you do it". Pretty much textbook hypocrisy.
p.s. For those wondering why the States need their own laws, when a federal law exists: Some court case or other led to a decision that the federal law was not binding on State and local governments. This is mentioned in the Wikipedia article about the federal law.
