I think you’re right.
The Justices often use questions to help push their colleagues one way or another. Kennedy, and to a lesser extent Roberts, are fence-sitters on this.
The Justices also aren’t immune from seeing what’s going on outside the Supreme Court Building. I think it unlikely that they are unaware of the various Christian small businesses that are being targeted.
So cue the Star Wars squid with the “Its a Trap!” quotation.
It would be, IMHO, poetic justice if Progressive overreach on this part of the issue pushes Kennedy and Roberts towards a more restrained decision than would otherwise have been the case.
I am praying hard that you’re correct. But the left always presses its advantages, no matter how unpopular it may be at the moment. They didn’t fight that hard just to give up ground. They will just bring the apathetic, distracted, majority of the public along after they enact the law. See CommieCare. They will suppress voices of opposition until the public believes that everyone thinks it’s a good thing (and the ones who still don’t believe it, believe themselves to be isolated), because most people are sheep.
