Employers should not be able to ask their employees to sign a contract rejecting legal choices. Personal choices that do not affect their work, or their ability to live a legal life outside of the bounds of employment. I'm just disgusted, and I hope they are ashamed of themselves.
Their motto is "transforming lives through Christ." I'm not sure what Bible they read, but the Christ I know taught by example, showing compassion and kindness to all, not just the popular folks. He told us we must not judge others, because we can also be judged and quite harshly, when we lack compassion.
