Whenever I interact with any individual, I want my part of the interaction to be loving. No matter who they are, no matter what sins they may or may not be working through in their life, I pray that I will love them.
Whenever the government legally requires me to love, it commits a grievous evil that hurts me, hurts the people I interact with, and causes pain to God.
Freely chosen love is the way to follow Jesus. Trying to force love is morally wrong.
