Morality is subjective and personal, ethics are codified by institutions and are situational, legality is dependent on the state.
I believe these are good and useful definitions.
If you don’t like what someone does ask yourself how does this hurt me. If it obstructs your life adversely seek legal action. If the laws don’t exist lobby your representatives. If it doesn’t hurt you just leave it alone. Keep to your ethics and morals and let other people live their lives as they see fit. If you do stick your nose in expect to get a response you won’t like. People have every right to fight for and defend their freedoms.
But this is where I argue, as I promised to do in the beginning. Just because something hurts you does not mean what they do is or should be illegal. Surgery hurts. Dental work hurts. Disciplinary action at work obstructs one’s life.
If it doesn’t hurt you but it hurts someone else, why should I not take action? Could not more Germans have taken action when the Jews of the Third Reich were having their rights removed further and further? It didn’t hurt those non-Jews, but perhaps they could have done something.
If someone else’s differing morals do not affect you directly, but you feel they adversely affect your society, are you not obliged to fight against their personal beliefs and moral code? They have the right to fight back, but fighting back implies you have the right to fight them in the first place.
