Again, I agree.
Besides, I have to wonder....why would a parent even WANT their child in the care of someone who doesn't even want them there?? Fighting it and suing you for it isn't gonna make you WANT to care for that child any more. If anything, it will just make you resentful. I don't know about you, but I would never want my kids in the car of someone who was basically FORCED to take them on.
Hell, I know Medical Doctors who refuse to care for unvaxed kids. Sure, they might not be legally allowed to refuse service but they still DO and I can tell you they ARE still in business. Why should WE be any different???
