A few examples of taboo would be incest relationships and abortion. Homosexuality was a major taboo especially a long time ago, but in the modern society, we have learned to accept diversity in culture and gender. But nowadays, incest and abortion are two things that violates the moral law and the social norms. On the otherhand, in some places, incest relationships are tolerated in order to continue the their family's name and to keep it within themselves.
