Because wanting to own other humans, killing people because of their race, gender or sexual orientation are not morals.
noun - a person's standards of behavior or beliefs concerning what is and is not acceptable for them to do.

There are cultures and religions around the world that live life differently from you. They believe there should be strong gender norms, have strict codes of conduct for how to live their lives, and expect and enforce those standards on everyone in the community. Do you think they should be silenced?
