When most people say that, they mean using the government to force everyone to follow "traditional morality". Which usually means outright banning everything that isn't "get married with children as soon as possible and observe gender stereotypes". Things have changed dramatically since the summer of 2020. People I know in real life used to find, for example, that the reverse sexism leftists subscribe to is a serious threat to true equality. But now those very same people will call you a leftist if you think men and women should have the same rights. They say they "WOKE up".
