If you can force a baker out of business because they discriminated against an LBGT couple you now have precedence on discriminating against about anything you can imagine. I say sue the coffee shop and put them out of business just like the baker.
No, 2 wrongs don’t make a right. It wasn’t right to force the baker, and it isn’t right to force the coffee shop. Repeat after me, “It’s a free country.” A favorite saying from my childhood that has unfortunately been replaced by the liberal mantra, “there ought to be a law.” Let’s bring freedom of association back. For everyone.
