We can educate people about healthy relationships. Teach them that all relationships should be based on equality and mutual respect.
We should start from our own communication. When talking with friends, family or in public, firmly oppose any form of relationship that involves coercion or non - consensual elements. Also, support laws and policies that protect the rights of individuals, and encourage the media to promote positive and healthy relationship models instead of such immoral ideas.
One way is to promote awareness of human rights. Make it clear that any form of slavery, including sexual slavery, is illegal and immoral. We can also support organizations that fight against human trafficking and exploitation which are related to such wrong ideas.
